I am a faculty member in the School of Technology and Computer Science at Tata Institute of Fundamental Research, Mumbai.

Before joining TIFR, I obtained my Ph.D. in Computer Science from University of California, Berkeley where I was advised by Prof. Sanjam Garg . Before that, I completed my undergraduate studies in Computer Science and Engineering at Indian Institute of Technology, Madras.
