I'm an associate research scholar at the Center for Information Technology Policy (CITP) at Princeton University and an external fellow at the International Computer Science Institute. I previously completed my Ph.D. as a member of the MOMENT lab at the University of California, Santa Barbara. I'm also co-founder and CEO of Invisv.

My research focuses on networked systems architecture; protocol design; privacy; traffic inference and performance analysis; and scalable Internet measurement. I take a dirty-slate approach to networked systems research, allowing for compatibility and immediate deployability in current environments.
