Personal

I am currently a 3rd-year Ph.D. student in the Department of Computer Science. You can see some photos of my family, as well as photos from my time in the Peace Corps (more).

Problems

I help maintain the cs department wiki, a repository of questions, answers, problems, solutions, ideas, complaints, and documentation about our department IT infrastructure.

Research

Credence Addressing content pollution in peer to peer filesharing through distributed ratings.

SNS: Staged Simulation A project to improve the scale and performance of discrete event wireless-network simulators.

Modelnet A large scale wide-area network emulator built from commodity hardware.

MagnetOS A distributed operating system for ad hoc and sensor networks to enable power-aware, adaptive, and efficient ad hoc networking applications.

My committee consists of Gün Sirer (chair), Ken Birman, Andrew Meyers, and David Henderson (Mathematics)
