Research Interests

Prof. Zegura’s research concerns the development of wide-area (Internet) networking services and 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.

Biographical Sketch

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. From February 2003 to Fall 2005, she was an Associate Dean, with responsibilities ranging from Research and Graduate Programs to Space and Facilities Planning.  She spent five years as the user representative in the planning of the Klaus Advanced Computing Technologies Building, which opened in Fall 2006.  She currently chairs the School of Computer Science in 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 didn’t make it on the web until facebook.  Outside of work, she enjoys quilting and Bikram yoga.


Current Research Projects

DOME: Diverse Outdoor Mobile Environment.  A DARPA funded project in mobile wireless networking in challenged environments.  Joint with Mostafa Ammar (GT), Brian Levine (UMass Amherst) and Mark Corner (UMass Amherst).


Wireless and Mobile (WAM) Continuum.  An NSF funded project in categorizing mobile and wireless networks in a multi-dimensional space and using the categorization to optimize operation for current conditions.  Joint with Mostafa Ammar.


Netmark. A project to reconsider network topology modeling from a structural standpoint by starting from global structural properties.  Follows on work in the mid 1990s that led to GT-ITM, a widely used tool for generating Internet-like topologies.  Joint with Santosh Vempala.


Internet for Everyone Really (IFER). A project to conceive a future Internet architecture for all 6 Billion of the world’s people, starting from considerations of the 3 Billion not currently reached by the Internet. 

Compute For Good (C4G)

Compute for Good (C4G) is an effort to leverage computing to study and address pressing societal problems.   The C4G vision is that computing and related disciplines can play a critical role in addressing systemic societal problems, and that tackling such problems can push the intellectual boundaries of the disciplines.  One realization of C4G is a project-based senior/graduate class that has been taught twice. See http://computingforgood.wordpress.com for the C4G Blog and
