Ellen W. Zegura received the B.S. degree in Computer Science (1987), the B.S. degree in Electrical Engineering (1987), the M.S. degree in Computer Science (1990) and the D.Sc. in Computer Science (1993) all from Washington University, St. Louis, Missouri. Since 1993, she has been on the faculty in the College of Computing at Georgia Tech. She was an Assistant Dean in charge of Space and Facilities Planning from Fall 2000 to January 2003. She served as Interim Dean of the College for six months in 2002. Since February 2003, she has been an Associate Dean, with responsibilities ranging from Research and Graduate Programs to Space and Facilities Planning.  She has spent five years as the user representative in the planning of the Klaus Advanced Computing Technologies Building, scheduled to open in Fall 2006.  Starting in August 2005, she has chaired the Computing Science and Systems Division of the College of Computing.  She is the proud mom of two girls, Carmen (born in August 1998) and Bethany (born in May 2001), whose pictures have never made it onto the web.

Prof. Zegura’s research work concerns the development of wide-area (Internet) networking services and, more recently, mobile wireless networking.  Wide-area services are utilized by applications that are distributed across multiple administrative domains (e.g., web, file sharing, multi-media distribution). Her focus is on services implemented both at the network layer, as part of network infrastructure, and at the application layer.  In the context of mobile wireless networking, she is interested in challenged environments where traditional ad-hoc and infrastructure-based networking approaches fail.  These environments have been termed Disruption Tolerant Networks.  More detail can be found on her publications page.
