I am an Assistant Professor in
the School of Computer
Science at Carnegie
Mellon University, with my primary appointment in the
Software and Societal
Systems Department (with
Computing program), and affiliated appointments with
the Machine Learning
Interaction Institute. I am also affiliated with
the CyLab and
I work on algorithms and machine learning. My recent work focuses on (1) how to make machine learning better aligned with societal values, especially privacy and fairness, and (2) how to make machine learning more reliable and robust when algorithms interact with social and economic dynamics. I study these questions using methods and models from learning theory, optimization, statistics, differential privacy, game theory, mechanism design, and human-computer interaction. For more details, please see my publications.
My research has been generously supported by the National Science Foundation (NSF), the Okawa Foundation, CMU’s Block Center for Technology and Society, an Amazon Research Award, a Google Faculty Research Award, J.P. Morgan Faculty Awards, Meta Research awards, a Mozilla Research Grant, Apple, and Cisco Research.
Previously, I received a Ph.D. in Computer Science in 2017 from the University of Pennsylvania, where I was extremely fortunate to have been co-advised by Michael Kearns and Aaron Roth. My doctoral dissertation titled "Data Privacy Beyond Differential Privacy" received Penn's Morris and Dorothy Rubinoff Award for best thesis. Before joining CMU, I was an Assistant Professor of Computer Science & Engineering at the University of Minnesota for two years. Before that, I spent a year as a post-doctoral researcher at Microsoft Research-New York City in the Machine Learning and Algorithmic Economics groups. Please see my CV for more details.
Our paper Confidence-ranked reconstruction of census microdata from published statistics is now published in PNAS.
One paper accepted at AIStats 2023 and one paper accepted at ICLR 2023.
