I am a Research Scientist in the Department of Computer Science at the University of Chicago working with Ben Zhao and Nick Feamster. My research focuses on robust and reliable machine learning. I am also interested in the application of machine learning to problems of societal interest. I completed my Ph.D. under the supervision of Prateek Mittal in the Department of Electrical and Computer Engineering at Princeton University. I spent five wonderful years at the Indian Institute of Technology Madras in a Dual Degree (B.Tech.+M.Tech.) program in Electrical Engineering. For an accessible overview of my research, see Research and for a full list of papers, see Publications.
