I am the Henry Salvatori Professor of Computer and Cognitive Science at the University of Pennsylvania computer science department. I also hold a secondary appointment at the Department of Statistics and Data Science at the Wharton School, and I am associated with the theory group, PRiML (Penn Research in Machine Learning) the Warren Center for Network and Data Sciences, and am co-director of our program in Networked and Social Systems Engineering. I am also affiliated with the AMCS program (Applied Mathematics and Computational Science). I spent a year as a postdoc at Microsoft Research New England. Before that, I received my PhD from Carnegie Mellon University, where I was fortunate to have been advised by Avrim Blum. My main interests are in algorithms and machine learning, and specifically in the areas of private data analysis, fairness in machine learning, game theory and mechanism design, and learning theory. I am the recipient of a Presidential Early Career Award for Scientists and Engineers (PECASE), an Alfred P. Sloan Research Fellowship, an NSF CAREER award, a Google Faculty Research Award, an Amazon Research Award, and a Yahoo Academic Career Enhancement award. I am also an Amazon Scholar at Amazon Web Services (AWS). Previously, I was involved in advisory and consulting work related to differential privacy, algorithmic fairness, and machine learning, including with Apple and Facebook. I was also a scientific advisor for Leapyear and Spectrum Labs.
My lovely wife Cathy just got her PhD in math at MIT. At her insistence, I link to her website
