I am a fifth-year Ph.D. student in Computer Science at UC Berkeley. I am co-advised by Professor David Culler and Professor Raluca Popa. I work in the Buildings, Energy, and Transportation Systems (BETS) research group in the RISE Lab in the EECS Department. My research interests are in Systems, Networks, and Security.
I received my B.S. in Electrical Engineering and Computer Sciences at UC Berkeley. As an undergraduate student, I worked in the Software-Defined Buildings (SDB) research group, which was the predecessor to BETS.
