I joined BU Computer Science in Fall 2017. From 2007 to 2017, I was a (assistant, then associate, then full) professor of Computer Science and Engineering at the Pennslyvania State University, where I was part of the Theory of Computation and the Systems and Internet Infrastructure Security (SIIS) groups.
During Fall 2006, before coming to Penn State, I was Securing Cyberspace at UCLA's IPAM. Previously, I was a post-doc at the Weizmann Institute in Rehovot, Israel, hosted by Moni Naor. Before that, I did a Ph.D. in the Computer Science and AI Lab at MIT, under the supervision of Madhu Sudan.
