I am an assistant professor of computer science at Stony Brook University where I lead the Networking Research Group. My research interests are in the general area of computer networking and network measurement. Specifically, I aim to use insights gained through measurement to improve the security, reliability and performance of networks.

Recently, this has led me to focus on measuring online information controls: censorship, traffic differentiation etc. I'm also interested in understanding the nature of malware threats targeted at civil society organizations and measuring routing security. You can read more about these projects on the Networking Research Group and ICLab Web pages. I am also affiliated with the Systems group and National Security Institute.
