    I am a fourth year Ph.D. student in Computer Science at the Unversity of Washington, working with David Wetherall, Arvind Krishnamurthy, and Aruna Balasubramanian. I am particularly interested in understanding and improving network performance at end hosts, especially at the HTTP and/or Web page levels. In the past, I worked on Web privacy with Ben Greenstein and David Choffnes.

    I released my research tool Piigeon, a firefox extension that tells you whether your password is safe as you sign in. Check it out here.
