2 PROFESSIONAL EXPERIENCE AHMED KHURSHID Bangladesh University of Engineering and Technology (BUET) o Department: Computer Science and Engineering (CSE) o Position: Assistant Professor (August 2008 to March 2015) o Position: Lecturer (July 2005 to August 2008) o Responsibilities: Teaching one CSE course every semester in a class of around 120 students. I have taught Computer Networks, Operating Systems, Software Engineering, Object Oriented Programming Language and Computer Interfacing. Bangladesh University of Engineering and Technology (BUET) o Program: Cisco Networking Academy Program (CNAP) o Position: Instructor (January 2007 to August 2008) o Responsibilities: Conducting classes of CCNA-1 to CCNA-4 at BUET Regional Academy of Cisco Systems. RESEARCH EXPERIENCE VeriFlow: Verifying Network-Wide Invariants in Real Time o Advisors: Prof. Matthew Caesar and Prof. P. Brighten Godfrey o In this project I developed a tool to verify the effect of new rules before they are allowed to propagate into the network. The goal is to detect faulty rules in real time and prevent them from affecting network operations. Stealthy Traffic Analysis of Low-Latency Anonymous Communication Using Throughput Fingerprinting o Advisors: Prof. Matthew Caesar and Prof. Nikita Borisov o This project focuses on throughput-based attacks to reduce anonymity of flows traversing the Tor network. Here, I developed throughput measurement tools, performed a large-scale measurement study over the live Tor network, and performed statistical analysis of our proposed attacks. Debugging the Data Plane with Anteater o Advisors: Prof. Matthew Caesar, Prof. P. Brighten Godfrey and Prof. Samuel T. King o I developed and coded a static analysis technique based on satisfiability testing to detect and diagnose network faults using data-plane information. Making DTNs Robust Against Spoofing Attacks with Localized Countermeasures o Advisors: Prof. Carl Gunter, Prof. Matthew Caesar and Prof. Tarek Abdelzaher o This project deals with detecting address spoofing attacks in Delay-Tolerant Networks (DTNs) and proposes a few countermeasures. I used ns-2 to evaluate the performance of the proposed countermeasures. Improving Robustness of DNS to Software Vulnerabilities o Advisor: Prof. Matthew Caesar o This project uses software diversity to mask arbitrary faults caused by DNS software implementation errors. Performance Evaluation of the Illinois Cloud Computing Testbed o Advisor: Prof. Indranil Gupta o I evaluated the performance of the Illinois Open Cirrus cloud computing research testbed. I developed a throughput measurement tool and analyzed the performance of both the storage and communication facilities of this testbed. Page 2 of 5

3 Scaling Data-Plane Logging in Large Scale Networks o Advisors: Prof. Matthew Caesar and Prof. Klara Nahrstedt o This project deals with designing a scalable logging framework for data-plane information. I developed a compression algorithm that improves upon existing traffic measurement techniques such as NetFlow, and evaluated its performance using real traffic traces and the Click software router.
