:

I am an assistant professor in the Department of Electrical and Systems Engineering (as of July 2017). I hold secondary appointments in the Department of Computer and Information Systems as well as the Department of Statistics and Data Science at the Wharton Business School. I am also a faculty affiliate of the Warren Center for Network and Data Sciences.
Before joining Penn, I was a research fellow at the Simons Institute, UC Berkeley (program: Foundations of Machine Learning). Prior to that, I was a post-doctoral scholar and lecturer in the Institute for Machine Learning at ETH Zürich. I received my Ph.D. degree in Computer and Communication Sciences from EPFL.
