Dr. Zhang's Short CV
Dr. Xiaolan (Ellen) Zhang is an assistant professor of Computer and
Information Science at Fordham University.
She completed her undergraduate education at Peking University, P.R.China,
where she received her B.S. degree is Computer Science.
She earned her M.S. and Ph.D. degree in
Computer Science from
University of Massachusetts at Amherst.
Dr. Zhang has six year industrial experience, and has published
papers in conferences and journals in the area of Computer Networks,
more specifically, Disruption Tolerant Networks and multimedia
My general research interests are in the area of computer networks and
distributed systems. In particular, I have studied some fundamental
problems in the areas of Disruption Tolerant Networks and multimedia
In recent years, wireless networks have been increasingly deployed
in challenging environments, such as wireless sensor networks,
disaster relief team networks, and networks for rural area in
developing countries. Even in areas with infrastructure support,
peer-to-peer opportunistic contacts have been leveraged to provide
alternative network connectivities, information dissemination and
retrieval, and mobile social network communities to people on the go.
These sparse ad hoc networks (Disruption Tolerant Network, DTN) present
new challenges due to their dynamic topology and inherent resource
constraints. I am interested in studying fundamental problems
concerning such networks, including performance modeling
of epidemic style routing, benefits of network coding, and
mobility trace modeling etc.
In the area of multimedia streaming system, I have worked in the
design, implementation and performance evaluation of a multimedia
streaming proxy aimed to provide a research platform for various
