My research is about how to use data robustly, reliably, and responsibly. I'm aiming to build firm foundations, but with a focus on the questions that will be critical for real-world systems, which I study using a mix of tools from algorithms, cryptography, security, machine learning, and statsitics. I am particularly interested in data privacy and preventing false discovery in the empirical sciences.

I am a member of the Theory Group and the Cybersecurity & Privacy Institute.

My research has been generously funded by the National Science Foundation and Google.


I am fortunate to work with a number of talented students and postdocs. My current group consists of:


I am currently teaching CS 7880: Privacy in Statistics and Machine Learning

Courses I've taught in the past include:

I am also the proud recipient of the Ruth and Joel Spira Outstanding Teacher Award.


I am currently the Privacy and Anonymity Track chair for CCS 2021. I have served on the program committees of many conferences, including: IEEE S&P '21, CCS '20, ITC '20, FOCS '18, SODA '18, TCC '16, EC '16, TCC '15, STOC '15, and ITCS '15.

I also co-organize the Workshop on Theory and Practice of Differential Privacy, and differentialprivacy.org.
