Nilesh Tripuraneni

I'm a 5th-year Ph.D. student at U.C. Berkeley working with Michael Jordan. I'm broadly interested in machine learning, statistics and applications of machine learning in domains such as chemistry and biology. Before coming to Berkeley, I received an M.Phil in Information Engineering from the University of Cambridge where I was advised by Zoubin Ghahramani and a B.A. in Physics from Harvard University.
