Research interests

The design and analysis of distributed systems, especially as found in networking and operating systems. I'm interested in both correctness analysis and performance analysis.

One area of current work is a framework (SESF), based on assertional-reasoning, for writing correct distributed programs. I'm currently developing tutorial-level software for this framework, specifically, a suite of distributed programs and a testing harness.

Another area of current work is timestep stochastic simulation of networks of TCP and UDP flows. Unlike traditional packet-level simulation, the network state is updated probabilistically at steps of time. This results in fast simulation, especially for high-speed networks. Details and a simulator (tssnet) are available here.
