Short Biography

Abdou Youssef received the B.S. degree in Mathematics from The Lebanese University, Lebanon, in 1981, the M.A. and Ph.D degrees in Computer Science from Princeton University, Princeton, NJ, in 1985 and 1988, respectively. He taught for a year in 1982 at the Institute of Applied Sciences, The Lebanese University. He has been with the Department of Computer Science (formerly Department of Electrical Engineering and Computer Science) at The George Washington University, Washington DC, since 1987, serving as Assistant Professor from 1987 to 1993, Associate Professor starting from 1993 to 1999, and Professor since 1999.
His research interests have been in the areas of search & retrieval, image and audio processing, data error recovery, watermarking, interconnection networks and computer architecture, parallel processing, fault tolerance, and algorithms. He has published over a hundred papers in those areas, and co-edited a book titled "Interconnection Networks for High-Performance Parallel Computers", published by the IEEE Computer Society Press. The research has been funded by NSF, NSA, NIST and others. Along with his students he has developed a system that recovers from fax errors without retransmission. Recently, he has been creating a new math-search engine, which is first of its kind.
He has been invited to lecture and give presentations throughout the world, including Germany, United Kingdom, Canada, China, and Brazil. He is the recepient of six Teacher of the Year Awards from the Department and the School of Engineering and Applied Science at GWU. He is listed in the Who is Who Among America's Teachers, and is a senior member of IEEE.
