Research

I am a theoretical computer scientist. The focus of my research is how to make data analysis more reliable and better aligned with societal values. A particular focus of mine is statistical data privacy, which studies how and when we can analyze a dataset without revealing information about the individuals in that dataset. I am also interesting in how to prevent false discovery in the empirical sciences. I study these and other questions using tools from cryptography, machine learning, algorithms, and game theory.

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.

Advising

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


Teaching

I've taught a number of courses, including:

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

Service

I have served on the program committees of many conferences, including: Oakland '21, CCS '20, ITC '20, FOCS '18, SODA '18, TCC '16, EC '16, TCC '15, STOC '15, and ITCS '15.

I also organize the Workshop on Theory and Practice of Differential Privacy

Students and Advising

I have been fortunate to work with a number of talented students and postdocs.
