Adam Sealfon

I am a research scientist in the Algorithms team at Google Research. I am currently working on problems related to differential privacy. I am also broadly interested in algorithms, cryptography, and machine learning, particularly provable guarantees for data privacy, robustness and security.

I received a PhD in computer science from MIT, where I was fortunate to be advised by Shafi Goldwasser. At MIT, I was a member of the Theory of Computation (TOC) and Cryptography and Information Security (CIS) groups. I also have an AB in mathematics and an SM in computer science from Harvard University, where I was advised by Salil Vadhan. Before joining Google Research, I was a postdoc at UC Berkeley working with Jacob Steinhardt and Michael Jordan and affiliated with the Berkeley Artificial Intelligence Research (BAIR) group.
