Ariela Sofer received the B.Sc. in mathematics, and the M.Sc. in operations research from the Technion in Israel. She received the D.Sc. degree in operations research from the George Washington University in 1984. Dr. Sofer joined GMU in 1983 and since January 2002 has been Chair of the Systems Engineering and Operations Research Department. She is also affiliated with the Simulation Group at the ISIS Center, Department of Radiology, at Georgetown University Medical Center. Her major areas of interest are nonlinear programming, numerical optimization, and optimization in medical applications. She is also involved in various airport design problems. Dr. Sofer is President Elect and Secretary/Treasurer of the Association of Chairs of Operations Research Departments (ACORD). She is immediate Past Chair of the INFORMS Computing Society and she has served as Secretary/ Treasurer of the SIAM Special Interest Group on Optimization SIAG/OPT. She has served as Associate Editor of the Operations Research Journal, and is currently Associate Editor for Management Science. She was co-chair of the SIAM Conference on Optimization held in 2002 in Toronto Canada.
