1 Dr. Mohamed Ashour is an Associate Professor in the Civil Engineering Department of the College of Engineering at the University of Alabama in Huntsville (UAH). He received his Ph.D. in Civil Engineering (Geotechnical Engineering) at the University of Nevada, Reno in Dr. Ashour earned his M.S. in Civil Engineering (Structural Engineering). Such a combination of civil engineering background enhanced Dr. Ashour s ability to conduct research work on bridge foundations, soil-structure interaction, slope stabilization, bridge abutment, soil liquefaction and soil dynamics. Dr. Ashour has 15 years of research and teaching at the University of Nevada, Reno, West Virginia Institute of Technology, and UAH. Dr. Ashour has also 15 years of research experience with the California, Washington, Nevada, West Virginia and Alabama Department of Transportation. He has several papers published in journals and conferences on soil-structure interaction, soil liquefaction, soil modeling, laterally and axially loaded piles/shafts (bridge foundations), and retaining structures, and a number of research reports submitted to California, Washington, Nevada, West Virginia Departments of Transportation and the Army Corps of Engineers. Dr. Ashour s work on deep foundations is cited in AASHTO (Chapter 10). He is a licensed professional engineer in the states of California and Nevada. Dr. Ashour consulted on a number of national and international projects on foundation and soil liquefaction problems (California, Nevada, Washington and Italy). He also taught short courses and workshops on the design of deep foundations and delivered several presentations in conferences, meetings, and seminars. Dr. Ashour teaches a number of graduate and undergraduate courses on soil mechanics, foundations and earth structures. He is a member of the Deep Foundation Institute (DFI) and the American Society of Civil engineers (ASCE), and a reviewer for several journals.
