I'm a graduate student in the Department of Computer Science at Princeton University. I'm part of the Princeton HCI group, the Princeton Security & Privacy group and the Center for Information Technology and Policy (CITP).

Broadly speaking, I am interested in information privacy and its intersection with usability and policy. I work with Marshini Chetty, and also collaborate with Arvind Narayanan and Serge Egelman.
