3 Dean s Message assistant professors in electrical engineering and computer science, and one assistant professor in civil engineering. I am pleased to communicate with you again in this issue of the CUA Engineer. As I write this message, I have just completed the first year of my third four-year term as dean of the School of Engineering and witnessed another successful academic year filled with new developments, activities and achievements. I am very glad to report the highlights of as follows: In September 2009, the school launched the CUA CardinalEngineer, an online newsletter, published quarterly to inform its readers about the latest news of the School of Engineering. More information can be found at Robert (Bob) Kavetsky, who earned one bachelor s degree and two master s degrees from our school and currently serves as the CEO of the Energetics Technology Center, received the 2010 Engineering Distinguished Alumni Achievement Award at the annual homecoming luncheon in October In November 2009 I was elected a Fellow of the American Association for the Advancement of Science (AAAS) and went to San Diego in January 2010 for the induction ceremony. Regarding our international educational programs, during the spring semester 2010, six CUA engineering students went to Hong Kong to study at the Hong Kong Polytechnic University (PolyU) and two students from PolyU came to study at CUA under the existing student exchange program between CUA and PolyU. For the 2+2 programs with Vietnamese universities, we received five students from International University and one student from Danang University of Technology. Most 2+2 students stayed at CUA after receiving their bachelor s degree to pursue doctoral degrees and serve as research assistants to our faculty. Along with Most Rev. David O Connell, C.M. and Provost James Brennan, I travelled to Taiwan in June 2009 and visited several Taiwanese universities, including St. John University, Chung Yuan Christian University and Fu Jen Catholic University. Then the provost and I travelled to Vietnam and visited several Vietnamese universities that have partnered with our school. They included the International University, Saigon Technology University, Ho Chi Minh City University of Technology, and Danang University of Technology. In the fall semester of 2009, the school welcomed 84 new undergraduate students, including 13 transfer students, and 50 new graduate students. During the academic year , the school granted 59 bachelor s degrees, 67 master s degrees and three doctoral degrees. The back cover of this issue displays the names of the degree recipients. During the diploma distribution ceremony at Commencement in May 2010, students, parents and faculty viewed for the first time the names of all 2009 and 2010 graduates displayed on the recently inaugurated Wall of Achievement. We hope that the wall will promote an instant physical connection between the school and our graduates. The research productivity of our faculty continued to be impressive with their active participation in grantmanship, publication and service in technical and professional societies. With 45 research proposals submitted, the school received more than $2 million in new funding. The Accreditation Handbook was revised and a multiyear calendar was established to prepare the school for the next reaccreditation visit in October The school continued to carry out accreditation maintenance activities, including assessing program outcome and seniors taking the FE exam. In summary, I am very encouraged with the progress of the School of Engineering in the past academic year, including student enrollment, faculty productivity, international programs and development activities. I look forward to another successful year in and hope you enjoy reading this issue of CUA Engineer. Regards, Five new faculty members will join the school in August 2010, including an assistant professor in biomedical engineering, three Charles Cuong Nguyen, D.Sc.

4 Something in the Water As a severe drought that began in 2006 plagued California, the state diverted water from streams and rivers to irrigate the farms of the Central Valley. In 2008, a natural resources NGO sued the state of California, claiming that the transfer of water from the Sacramento-San Joaquin River Delta to the Central Valley had had a deleterious effect on striped bass and delta smelt by pulling fish eggs and fish from the streams in which they were spawning into the pumps. A federal court agreed and shut the pumps down. The courts found merit in the NGO s argument, but science s verdict was murkier: was it the pumps that had led to a downturn in the fish population or was it the drought itself, which continues in California? You can t test in nature, says Assistant Professor of Civil Engineering Arash Massoudieh, so, funded by the California Department of Water Resources, he and a team of researchers created a computer model to simulate the fish population and behaviors under conditions of both drought and stress brought on by water pumps. The model traces the lifecycle for striped bass in the San Francisco Bay and its delta. It integrates a distributed transport model for eggs and larvae in the delta with a lifecycle model in the bay to predict the effect of environmental factors such as chemical stressors, flow and pump operation on the abundance of striped bass, explains Massoudieh. The striped bass model also will be applied to longfin smelt, once one of the most abundant open water fish in the San Francisco Bay, now classified as endangered by the California Fish and Game Commission. Massoudieh hopes to develop additional models that simulate ecological systems using those submodels. Faculty Profile Water and its contaminants are at the center of Massoudieh s research. My interests lie primarily in modeling the fate and transport of contaminants in aqueous systems, including groundwater, surface water, vadose zone (water above groundwater but beneath the earth s crust), storm-water runoff, and sediment-water, particularly in how sediment and other solids facilitate that transport. In association with his work on pollution from highway runoff into water systems, Massoudieh is developing algorithms using computational models based on evolution to provide a framework for how storm-water runoff transports pollution from roads and where that pollution ends up. I m working on developing a model that considers both dissolved and colloidal phases of contaminants and what happens to the overall contaminant mass as those two phases interact, says Massoudieh, who holds a Ph.D. in environmental engineering from the University of California, Davis. Massoudieh also is studying how coagulation, break-up and settling of colloidal particles affect the efficiency of storm-water retention bases in removing metallic and organic contaminants from highway storm water. Massoudieh s move from California to the Mid-Atlantic region has brought him to the center of Chesapeake Bay country, where his research has especial application. The world s largest estuary, the bay is home to striped bass, menhaden and blue crabs. It also drains a huge watershed that is growing in population, bringing it under assault by all three of his primary concerns: contaminants, runoff and sediment. Assistant Professor Massoudieh s work on water looks at contaminants, run off and sediment. 2 cuaengineer

5 Shedding Light on It Faculty Profile Assistant Professor Ramella-Roman employs light in her research. Light will someday soon be used to define the exact borders of skin cancer, predict eye disease in diabetics and flag life-threatening circulatory problems for spinal-cord-injury patients, Assistant Professor of Biomedical Engineering Jessica Ramella-Roman says. Light is a critical tool because it allows researchers such as Ramella-Roman, postdoctoral fellow Paul L let, and Ramella-Roman s team of graduate students to see, measure and analyze tissue in a way that, unlike MRIs and X-rays, isn t damaging to the body. Ramella-Roman is one of two CUA professors working in bio optics, or biophotonics, a relatively new area of biomedical engineering that studies how body tissue responds to light. In her research, light is shone on a patient, penetrating superficial tissue. While some of this light is absorbed by the body, other light scatters and reflects back to a collection instrument such as a camera. Knowing that wavelengths of light are absorbed in different ways by different components of tissue, researchers analyze the light that is reflected back to determine properties of the tissue, such as its oxygen and water levels. If you can quantify those properties, then you have a very strong clinical understanding of what is happening in tissue... and you can make a number of diagnostic advances, the professor says. In the Bio Optics Lab in Pangborn Hall, Ramella-Roman is pursuing three lines of research: using spectroscopy (the study of the spectrum of light emitted or absorbed by matter) to measure oxygenation in the skin and retina; designing fiber-optic probes to shine and collect light; and using polarized light to highlight the borders of skin cancer. In the past few years, Ramella-Roman s lab and affiliated institutions have been awarded more than $2 million in grants. In a collaboration with Johns Hopkins University, for example, We re now involved in a clinical study that seeks to prove the hypothesis that deprivation of oxygen in the retina is one of the early signs of diabetic complications that lead to blindness, she says. In the past three years, she has been working with CUA colleagues, including L let, to design a system employing spectroscopy to accomplish something that s never been done before: measuring oxygen in the retina in a noninvasive way. Dr. Mohamed Ibrahim of the Wilmer Eye Institute at Johns Hopkins University says Ramella-Roman s research will expand knowledge about blood flow and oxygen consumption in the retina. Such findings will help physicians and scientists detect the earliest changes that happen in the retinas of people who suffer from diabetes, he says. The information from her research may also help future studies that aim at finding and developing therapies for patients with diabetic retinal disease. Ramella-Roman s goal is to create a system that would be used by an ophthalmologist in a hospital. If the clinical study proves our hypothesis is correct, then it would probably become a routine exam for diabetics. In another use of light, testing at the National Rehabilitation Hospital is determining whether a fiber-optic probe created by Ramella-Roman s research can provide clues to predict autonomic dysreflexia the life-threatening high blood pressure and circulatory condition that can result when a spinal-cordinjury patient experiences a stimulus in a part of the body below his injury. In this research, funded by the Christopher and Dana Reeve Foundation, Ramella- Roman is trying to prove that people who have autonomic dysreflexia have reduced oxygen in their skin. She hopes that a dysreflexia meter can be developed to flag symptoms and alert spinal-cord patients to the need for treatment. The Hairball, an apparatus with 16 tentacles that beams polarized light at different angles onto a patient s skin, was created by Ramella-Roman with the National Institute of Standards and Technology. The technique produces high-contrast images that could help surgeons better see the borders of skin cancer, reducing the discomfort and cost of biopsy surgery. Because light penetrates skin shallowly and then scatters, bio optics can be a frustrating field, Ramella-Roman notes. It s a real challenge to gather any type of information from the light that comes back. But it s definitely rewarding when information does result. It gives me great satisfaction to give clinicians new tools new eyes to work more effectively or to make diagnoses that might not be possible otherwise. fall2010 3

6 CUA s Engineering Dean Honored as AAAS Fellow Dean Nguyen and Nobel Laureate and AAAS president Peter Agre at the fellow induction ceremony in San Diego. Dean Charles Nguyen was elected a Fellow of the American Association for the Advancement of Science (AAAS). AAAS is the world s largest general scientific society. Members are nominated to be fellows by their peers and selected for their efforts to advance science and its applications. Nguyen was recognized for distinguished contributions to the field of robotics and automation, particularly for parallel robot manipulators and intelligent control. Named dean of engineering in 2001, Nguyen served as chair of CUA s Department of Electrical Engineering and Computer Science for almost four years. He was appointed by President George W. Bush to be a member of the Board of Directors of the Vietnam Education Foundation for a three-year term from 2004 to 2007 and traveled extensively in that capacity to Asia, especially Vietnam, to develop educational programs. Being an administrator for the past several years, Nguyen said, I am humbled and honored to receive this recognition from AAAS, especially given that my peers in AAAS recognize the research work I did in robotics and automation years ago. In addition to his research and founding of a major journal titled Intelligent Automation and Soft Computing, Nguyen has published more than 100 technical and scientific papers in the area of control and robotics, co-edited three books and guest-edited 10 special issues in major journals. He was the chairman of the Robotics Committee of the Fifth International Symposium on Robotics and Manufacturing in 1994 and the program vice-chair of the Institute of Electrical and Electronics Engineers Conference on Robotics and Automation in Nguyen and other newly named fellows were honored Feb. 20, 2010, at a Fellows Forum during AAAS annual meeting in San Diego. Ecosystem Cleanup and the National Kuwaiti Students Jeffery Giangiuli, director of CUA s Engineering Management Program, addresses students. On Feb. 2, 2010, Jeffrey E. Giangiuli, director of the CUA Engineering Management Program, along with Diane Murphy, chairman of the Marymount University Department of Information Technology, briefed approximately 50 students from the National Union of Kuwaiti Students (NUKS) on Technology and its Application in Your Life. Murphy s PowerPoint presentation on the evolution of technology emphasized the current use of the myriad wireless technologies available not only to NUKS students but also to students all over the world. Giangiuli s presentation focused on applying environmental technologies to the cleanup of the Kuwaiti ecosystem damaged during the exit of Iraqi troops during the first Gulf War. The challenge facing the Gulf states is determining which technologies to use to repair and restore the aquifer and the desert pavement as well as to remediate the oil lakes, tarcrete and unexploded ordinance still remaining there. This enormous technical, financial and political challenge prompted a lively discussion among the students. In his presentation, Giangiuli discussed the role of the Program Planning and Supervisory Consultant in evaluating and testing those new technologies for the clean-up job in Kuwait. 4 cuaengineer

7 Taiwan and Vietnam Welcome CUA Delegation In June 2009, Dean Charles Nguyen and Professor Frank Pao, director of international programs, traveled to Taiwan with CUA s president, Very Rev. David M. O Connell, C.M., and Provost James Brennan. The CUA delegation attended Chung Yuan Christian University s commencement in Jhongli, Taiwan, on June 13. There Father O Connell delivered the graduation address and received an honorary doctorate. The next day, Father O Connell concelebrated Mass with Archbishop of Taiwan John Hung Shan-chuan, who is a CUA alumnus. In the evening, the CUA delegation enjoyed dinner with about 20 CUA alumni who live in Taiwan. At the dinner, Father O Connell presented Most Rev. Hung with a Certificate of Presidential Recognition for outstanding alumni. Other notable alumni attending the event included General Ko-Kung Chu (retired), Professor Bo-Cheng Wang of Tamkang University and Professor John Chu of St. John s University. During the stay in Taiwan, Father O Connell signed memoranda of understanding with Chung Yuan Christian University and with St. John s University in Taipei, Taiwan, paving the way for future academic collaboration with these two institutions. On June 16, Provost Brennan and Dean Nguyen traveled on to Ho Chi Minh City, Vietnam, and met with Cardinal Jean-Baptiste Pham Minh Mân. Later they attended a dinner with clergymen who are CUA alumni, including Bishop Pierre Nguyen Van Kham. In addition, the two CUA leaders met with administrators of the Vietnamese universities Saigon Technology University, International University and Ho Chi Minh City University of Technology in Ho Chi Minh City, Danang University of Technology University in Da Nang and Hanoi University of Technology and several research centers in Hanoi. They signed memoranda of understanding between CUA and the above institutions. During their stay in Ho Chi Minh City and Danang, the provost and the dean met with the prospective students and their family members and also conducted interviews with the students.

8 Mechanical Engineering in the Field On Nov. 16, 2009, 32 undergraduate students, several graduate students, as well as CUA Department of Mechanical Engineering faculty and staff got a firsthand look at engineering in action at the Chalk Point Power Generating Plant in southern Prince George s County, Md. Arranged through the ASME Student Chapter, the tour was facilitated by recent mechanical engineering graduate Kevin Milsted, who works at Mirant Company, which owns the plant. Chalk Point is the largest power-generating station in the Washington region, spanning 1,160 acres. Of the 278 workers at the plant, 10 are engineers who oversee the station s day-to-day operations. Students and faculty alike were amazed at this 18-story, manmade metallic machine, which has the capacity of generating 2,413 megawatts of power, supplying electricity to 2.4 million people and burning up to 5,000 tons of coal per day. The tour of the facility allowed the students to see different disciplines of engineering at work, from the magnificent structures designed/built by civil engineers, to the combustion and pollution-control machinery designed and operated by mechanical engineers, to the electricity-dispatching control/distribution to end users by electrical engineers. Having already learned in their coursework about the different components of a power-generating plant, seeing them actually performing their designated tasks clarified students understanding of how a full-scale, real-life power plant operates. This educational trip bridged the gap between learning about engineering and seeing the actual functions performed by engineers.

9 High School Students Get Hands-on Experience in Engineering More than two dozen Virginia high school students were introduced to Catholic University s School of Engineering thanks, in part, to the cartoon characters Tom and Jerry. To illustrate an application of computer science, Assistant Professor of Electrical Engineering and Computer Science Jae Choi led students in a computer-game programming exercise. When the teams of students programmed the game correctly, the well-known characters Tom and Jerry appeared on computer screens. Choi, who has a background in computer graphics, developed the exercise so that the game could be transferred to an Xbox 360. It was fun. I learned to do functions, said Erf Islam, who with his team was able to complete the program and have Tom grab Jerry. His teammate, Sandy Janwatin, said, It was interesting. It s nice to learn some programming and see how it comes out in the end. The two juniors from T.C. Williams High School in Alexandria were among 27 students who visited the campus on Dec. 14, 2009, to learn more about CUA and the fields of computer science and electrical engineering, and how they can use the majors in specific careers. I think for the students to see some hands-on applications is good, said Jennifer Moshier, who teaches advanced research and design and introduction Assistant Professor Jae Choi works with high school students, from left, Sandy Janwatin, 17, Gabriel Hendrickson, 16, and Erf Islam, 16, to create a computer game program. to engineering at Alexandria s only public high school. She and Shelly Bell, who teaches AP computer science at Williams, accompanied the students. The high-schoolers were welcomed to campus by Dean Charles Nguyen. Hands went up when he asked students whether they were good in math and science. Have you ever wondered whether you can apply math and physics equations to building something useful like a space shuttle or a race car? Nguyen asked. To illustrate just what one can do with an engineering degree, Nguyen called on Professor Phillip Regalia, chair of the Department of Electrical Engineering and Computer Science, and Professor Sen Nieh, chair of the Department of Mechanical Engineering, who showed off current technologies and explained the work of engineers. Assistant Professor Lin- Ching Chang outlined the growing demand for engineers in the workplace. The four professors, who spent the morning with the high school students, represented full-time engineering faculty, all of whom hold doctoral degrees and regularly conduct research and write for publications. The students also toured the School of Engineering, which has more than 6,000 alumni, and heard from representatives of the athletics and admissions offices. The visit, which was coordinated by Carol Young, a recruiter in the School of Engineering, marked the end of National Computer Science Education Week. CUA Hosts ASCE Conference CUA Concrete Canoe team. Each year one student chapter affiliated with the Virginia section of the American Society of Civil Engineers (ASCE) hosts a conference that brings students from 11 schools together to compete against each other in a array of civil engineering-related events. CUA hosted this year s conference from April 8 to 10, More than 250 students and faculty advisers from schools located throughout D.C., Virginia and West Virginia participated in an array of activities. In addition to CUA, the other schools included Bluefield State College, Fairmont State University, George Mason University, George Washington University, Howard University, Old Dominion University, University of Virginia, Virginia Military Institute, Virginia Polytechnic University, West Virginia University and West Virginia Institute of Technology. Over the course of the three days, students participated in concrete canoe, steel bridge, surveying on the National Mall, concrete bowling, oral presentations, mystery designs and team-building exercises. The last day of the conference featured an awards banquet. CUA s steel bridge team placed third out of nine teams. Generous donations from ASCE s National Capital Section, the Clark Construction Group, LLC, the Washington Court Hotel, CUA s School of Engineering and Department of Civil Engineering, and CUA alumni made this event possible. fall2010 7

10 Student Research: Robust Optimal Adaptive Routing for Traffic Networks Measures to relieve congestion are generally based on the concept of making the best use of current infrastructure through advances in information technology. That concept is the foundation for the idea of intelligent transportation systems (ITS). One sub-system of ITS, advanced traveler information systems (ATIS), aims to provide travelers with updated and useful information about traffic network conditions in the hope that a better informed traveler can make a better decisions and better decisions by many travelers would result in a relief from congestion. The value of ATIS is most evident when traffic conditions are stochastic or uncertain as found after accidents, in work zones, during breakdowns, in bad weather, or during special events, when scheduling vehicle routes is a particular problem. In uncertainty, drivers are concerned about the reliability of projected travel times. This research considers the risk-taking/aversion behavior of the drivers during optimization of travel time and route selection. The objectives are to design algorithms, optimize policies and suggest reliable routes based on the combination of minimum expected travel time and other important criteria. In other words, this study applies statistics and optimization techniques and uses advanced information and communication technologies in transportation to improve travel convenience and efficiency by suggesting better routes in the context of reliable minimum travel times. One interesting application of this study is helping the transportation industry develop more accurate and adaptive global positioning system. Mostafa Ardakani demonstrates how the ATIS will improve driver behavior. Mostafa Ardakani joined CUA in 2007 as a visiting scholar with the Department of Civil Engineering, and is currently working on his second Ph.D. He earned his first Ph.D. in industrial engineering from Iran University of Science and Technology, a prestigious university in his native city of Tehran. He excels in software and mathematical analysis and simulation, and is currently funded by the National Science Foundation for research in travel time and driving behavior. Tull Honored as Hometown Hero for Swift Water Rescue While most NCAA football players can often be found lifting weights or downing powdery protein shakes, Catholic University sophomore John Tull discovered another way to spend his offseason. The Pennsylvania native has worked as a volunteer firefighter for the last five years for the Middletown Fire Company in Media, Pa. I believe that firefighting, like football, is a brotherhood, says the offensive lineman. It s just like stepping on the football field, knowing your teammate next to you is fighting for the same thing and has your back. While Tull has been at the scene of numerous vehicle rescues, building fires and other medical emergencies, he found himself in an unprecedented life-or-death John Tull, B.M.E situation on Dec. 26, That afternoon, an SUV plummeted into the freezing waters of Ridley Creek with a mother and her 14-year-old daughter. Tull was among the first responders to the scene. When he arrived, he saw a mother trapped in her car while her daughter clung to a tree in the raging waters 20 yards away. Thirty-two minutes after the call had been made, the team reached the teenage girl, placed her in a rescue basket, and lifted her 200 feet to safety. They then rescued the mother, who was clinging to a cell phone and crying as the water level increased in her vehicle. They were both taken to the hospital and treated for minor hypothermia, but were released later that day. Seeing a girl clinging for her life was shocking, Tull said. Composure was vital in effectively rescuing the girl and her mother, and I believe a lot of that comes from my various football experiences. This incident was definitely the most hazardous and dramatic rescues I have ever been part of, he said. Although the offensive lineman was captain of his high school swim team, he believes that braving the cold waters had little to do with his swimming abilities. Swimming helped very little in this situation. It was all up to the strength and power I had gained in training for football. As a key member in the success of the dangerous rescue, Tull received a Township Letter of Commendation and a County Citation for Heroism. He was also honored with an Award for Valor from the Delaware County Fireman s Association. We did what we had to do with the resources we had at our disposal, and at the end of the day, everyone went home safely, Tull notes. You can t ask for much more. 8 cuaengineer

11 Mathews Podcasts Keep Coursework Flowing Last year in response to the N1H1 influenza outbreak, CUA s provost asked professors to create contingency university emergency closing plans. Associate Professor of Electrical Engineering Scott Mathews responded with Pedagogical Podcasting. Throughout the spring 2010 semester, Mathews used electronic lecturing techniques in his 500-level electrical engineering course to create podcasts of every lecture, which were then posted to the Internet. In addition to using a traditional textbook and the video podcasts, Mathews presented most of the classroom material in Microsoft Powerpoint, augmented with online animations and demonstrations. Associate Professor Mathews giving a classroom lecture that is being recorded for video podcasting. Mathews also began using screen capture software and a tablet pen, which allowed him to write or draw on top of Powerpoint slides, in real time, while recording both the video from the computer screen and the audio of the lecture. Says Mathews, Posting the podcast, the lecture slides, and the supplementary material using the Blackboard 8 software gives students access to all the course material, including the complete lectures, at any time via the Internet. Several graduate students in the class were full-time, working professionals who missed class because of work-related travel. Access to all the course material essentially meant that they did not miss a lecture. Other students found it very helpful for review. The success of Mathews podcasting and other electronic techniques led to his giving a seminar that included discussions about hardware and software, reducing podcast file size, uploading and file sharing issues, Mac vs. PC compatibility, and general tips about podcast lecturing to the engineering faculty. Mathews says, These Internet-based techniques can supplement traditional teaching, not replace it. In the case of an extended university closure, these techniques would allow lectures and coursework to continue Senior Design Day Brings Out Engineering s Best On May 3, 2010, the CUA School of Engineering held its second Senior Design Day, a daylong event to showcase senior design projects from each of the four departments. During the conference-style forum, groups of students present yearlong projects to each other and the university community, including engineering faculty and engineering alumni. During the year the students worked in groups of two or three on projects that demonstrate professional application of formal academic skills to an open-ended problem. The problems they confront require them to apply not only the mathematics and physics knowledge they have acquired at CUA, but also practical skills, including working with others, scheduling and budgeting. Their communications skills are also on display through traditional reports, conference-style presentations and online documents to explain the process that led to their final design. This year, each group gave a 15-minute presentation and discussed their work in an open poster session where the students and the community could talk about the projects in an extended way. Fifty-three students produced 21 projects that covered topics such as concrete construction for civil structures, musical instrument design, vehicle design for both underwater The winning civil engineering team at senior design day competition. autonomous systems as well as all-terrain vehicles. Alumni judges awarded prize money for winning projects in each department.

12 CUA Solar Panels Electrify Educational Tools As 1,000, 3-by-6-foot solar panels were being installed on roofs of four buildings at CUA in December, Associate Professor of Electrical Engineering Scott Mathews was thinking about how to leverage them into educational experiences. Mathews came up with a few ideas. The first was a tour of the installation shortly after it was completed for students in the Alternative Energy Program he directs at the School of Engineering. To have students see a real installation is a very valuable teaching experience, he says. The other was a design competition for something he thought students would find useful on campus: a solar picnic table with electronic capabilities. He ran the idea for the competition past Brian Alexander, director of energy and utilities management, who lined up support from Washington Gas Energy Services and Standard Solar, the Gaithersburg, Md., company that installed the panels, as well as the schools of engineering and architecture and planning. The winners of the competition were announced at CUA on Earth Day, April 22. The winning team designed a functional picnic table capable of supplying and storing power generated by solar-energy panels, using as their inspiration the contemporary design of the Edward J. Pryzbyla University Center. Chosen by a panel of CUA s faculty and staff and executives from Standard Solar Inc. and Washington Gas Energy Services (WGES), the team was awarded $3,000. An actual picnic table will be produced from their design and placed in front of the Pryzbyla Center. The winning team was made up of a graduate student in mechanical engineering, Joseph Cochrane of Coopersburg, Pa., and five students in the Master of Architecture and Master of Science in Sustainable Design programs: Lindsey Dickes of Baltimore; Michael Doster of Wayne, N.J.; Cory Estep of Bradenton, Fla.; John Lang of Ellicott City, Md.; and Monica Perez of McLean, Va. Their design incorporated five solar panels that they predicted would generate enough energy to power two laptops and two ipods at any given time. Real-time data on energy generated and consumed would be digitally displayed for users. Second place model in Solar Design competition. Sixth-Graders Get Inside Look at Engineering from Robot Maker Dean Nguyen demonstrates to students how robots work. 10 cuaengineer More than 30 middle- and high-school students from Northern Virginia got a hands-on lesson in robotics during a visit in May to Catholic University s School of Engineering. Who better to explain what CUA students are doing in the field of robotics than the dean himself, Charles Nguyen, who demonstrated how robots work. Robotics is the research specialty of Nguyen, an American Association for the Advancement of Science Fellow. This is an effort of our school to help improve STEM (Science, Technology, Engineering, and Mathematics) education in the United States by inspiring students to explore those disciplines, he said. Visitors included members of the sixth-grade compacted math class and the after-school robotics club at Poe Middle School in Annandale, Va. Compacted math is an accelerated program that is offered to select sixth-

13 Ph.D. Student Credits CUA For Accomplishments Kandahar, Afghanistan, isn t where Andrew Riel (B.E.E. 2007, M.E.E. 2008, M.S.E. 2009) thought he would be working when he joined the Johns Hopkins University Applied Physics Laboratory (JHU/APL) after graduating from The Catholic University of America in Located in Laurel, Md., JHU/APL is a not-for-profit center for engineering, research and development, which acts as a technical adviser to the government in areas ranging from undersea warfare to space exploration and everywhere in between, says Riel. In the spring of 2009, the federal government asked JHU/APL to send a representative to Afghanistan to serve in a technical advisory capacity. Riel, who calls himself a proud Catholic University graduate, was ready and willing to stepin and serve his country. His electrical engineering expertise gained him the unique opportunity to travel to the Middle East and serve this critical capacity for six months. After returning to the United States, Riel resumed his previous assignments at JHU/APL as a member of the National Security Technology Department. With three degrees from The Catholic University of Andrew Riel in Afghanistan as a technical adviser. America, Riel says, I malways eager to continue my education and am working toward a Ph.D. in electrical engineering, also at Catholic University. Riel s love of learning extends beyond the classroom. An avid aviator, he became a ground instructor holding both advanced and instrument ratings in 2002, earned a commercial pilot certificate two years later, and is currently pursuing his flight instructor certificate, which will add to his impressive repertoire of ratings in a variety of airplane classes. Riel is rated for singleand multi-engine land airplanes as well as singleengine seaplanes. Once he has completed qualifications for his flight instructor certificate, he plans to share his passion for flying. Riel happily credits his education at CUA. Whether in Maryland or across the globe, The Catholic University of America has had a large influence on my career decisions and personal interests. The lessons he has learned both in and outside of the classroom, he says, have shaped the person I am today and will continue to do so for years to come. graders in Fairfax County, Va. Joining them were sophomores from Thomas Jefferson High School for Science and Technology, a Fairfax County magnet school that has been named a Department of Education Blue Ribbon School. The high-schoolers are members of Thomas Jefferson s Botball Club who mentor the middleschool math students. Botball is an annual student robotics competition. Can you be an engineer? Nguyen asked the students in his introduction. He said the answer was an emphatic yes if they like math and science and want to apply what they learn to making something useful. He asked the students to imagine a world without TVs, DVDs, CDs, cars or cell phones. I would not want to live in that kind of environment, he said. The students agreed. Everything you see, he told them, has been created one way or another by an engineer. He explained that engineering is applied math and went on to tell students that math changed his life. Knowing the Pythagorean theorem, he said, gave him an idea in the late 1980s that led to the development of a robot for NASA. The dean showed off the robot he designed, along with others, in a lab in Pangborn Hall. Two CUA students displayed their senior-design project, a motorized device intended to take an objective measure of the muscle tone in the wrists of patients with Parkinson's disease. Theresa Murray of Vernon, Conn., and Marvin Gunawan of Glenn Dale, Md., gave youngsters a peek into the inner mechanics of the device designed by them and Kathryn Werner of Brooklyn, N.Y. The visitors also were able to learn about computer-game programming from Jae Choi, assistant professor of computer science (page 7). It is my hope that this visit will inspire students to continue their interest in robotics and engineering and that many of them will ultimately apply to Thomas Jefferson for high school, said Rod Harbin, a Poe Middle School math teacher who arranged the visit. The Thomas Jefferson students are, likewise, hoping to find inspiration for their own senior projects. fall

14 CUA School of Engineering Hosts Vietnamese Educators Thirteen educators from the University of Da Nang, Vietnam, spent Nov. 18 touring Catholic University s School of Engineering and meeting with its faculty and students. Dean Charles Nguyen welcomed the educators at a formal luncheon during the group s one-day visit. A memorandum of understanding was signed by the two universities in June 2009 when Nguyen and Provost James Brennan visited Da Nang. The agreement calls for the two universities to collaborate on research and to exchange faculty for lectures and students for course work. At the luncheon, Nguyen noted the special relationship between the two schools. Deans from various CUA schools and engineering faculty joined Nguyen, Brennan and the Vietnamese delegation at the luncheon at Pangborn Hall. At the luncheon, Provost Brennan told the visitors, who had traveled more than 8,700 miles, We re very honored to have you here. All this comes about because of the commitment of Catholic University to reach out to other cultures and to globalize our curriculum in ways that make our students well prepared to be citizens of the world. This is very much a part of that. I m so happy we are able to reciprocate the wonderful hospitality that was extended to us in June and to have you come to Washington to see our great city and our very special university. One of five regional universities in Vietnam, the University of Da Nang s technology school offers engineering degrees. Bui Van Ga, president of the University of Da Nang System, noted that two students from Danang University of Technology are pursuing doctoral degrees in CUA s Department of Electrical Engineering and Computer Science. In the future, we hope to send other undergraduate students and post-graduate students to the university because of the high-quality, excellent program, Ga said. Visitors to the CUA campus also included Tran Van Nam, rector of Da Nang University of Technology. The visiting educators met with students after touring the John K. Mullen of Denver Memorial Library and the Basilica of the National Shrine of the Immaculate Conception.

16 Faculty Honored at Year-End Luncheon The CUA School of Engineering honored five faculty members with the Kaman awards and Burns faculty fellowships at the year-end luncheon in May. The annual event was held in the Anthony T. Scullen Memorial Room. Attendees included faculty, staff, students and members of the university administration. The two recipients of the 2010 Burns Faculty Fellowship were Jae Choi, assistant professor of electrical engineering and computer science, and Gunnar Lucko, assistant professor of civil engineering. Choi s main research areas are 3D visualization and minimally invasive image-guided surgery that can enhance the accuracy of many medical procedures and surgeries. Lucko s research explores mathematical modeling, analysis, and integration of construction project schedules, costs, and operational plans. The Charles H. Kaman Faculty Excellence in Research Award went to two professors this year, Peter Lum, associate professor of biomedical engineering, and Joseph Vignola, associate professor of mechanical engineering. Lum uses engineering methods to assist development of novel interventions for rehabilitation of movement following neurological injury. He has been working in the area of rehabilitation robotics for more than 17 years, with emphasis on stroke survivors. Vignola s focus includes the analytic study of complex dynamic systems in manipulating the mechanical response of such systems, as well as acoustic detection of IEDS. The response-shaping research has applications that include MEMS dynamics, radio frequency band pass filters, robotic arm dynamics, ultrasensitive chemical vapor sensing and energy harvesting. Jessica Ramella-Roman, assistant professor of biomedical engineering, received the Charles H. Kaman Faculty Excellence in Teaching Award. This honor is distinct from the other faculty awards because candidates are nominated directly by their students and colleagues. Outside the classroom, Ramella-Roman conducts research primarily in biophotonics and bio-optical imaging faculty awards winners, (from left, front row) Professors P. Lum, J. Choi; J. Ramella-Roman, J. Vignola, G. Lucko. Staff Excellence Award This year, the School of Engineering established a School of Engineering Staff Excellence Award to recognize one member of the administrative staff who excels in all aspects of their job. The selection committee chose Ruth Hicks, assistant to the chair in mechanical engineering, as the 2010 inaugural recipient. She said she was shocked when learning she was the recipient because the school has such a fine workforce. I am privileged to be among them. Hicks has been with the school for more than 20 years and is deeply appreciated by all members of the engineering school community. When asked what she loves most about her job Hicks responded, Without a doubt, it is supportive faculty and the interaction with the students. The faculty and I have a mutual respect and appreciation for each other. They care what I think and welcome my input. As for the students, I care for them as if they were my own. Many times, parents thank me for being their mom away from home, and believe me, the privilege is all mine. Ruth Hicks accepts the first Staff Excellence Award from Dean Nguyen. 14 cuaengineer
