Sunoo Park ▪  J.D. Candidate @ Harvard Law School ▪  Ph.D. in Computer Science (Cryptography)
Background.
I am a final-year J.D. candidate (3L) at Harvard Law School and I do academic research in computer science (cryptography) and law and policy issues related to computer security and data privacy.

I completed my Ph.D. at MIT in 2018, advised by Shafi Goldwasser. During my Ph.D. studies, I was in the Cryptography and Information Security group within the Theory of Computation group at MIT, and also affiliated with MIT’s Internet Policy Research Initiative and with the Digital Currency Initiative at the MIT Media Lab (where I also did postdoctoral research from 2018 to 2020). I received my B.A. in Computer Science at the University of Cambridge.

This website describes my research and publications. I am interested in research both in law and in computer science, and especially on topics that relate to both fields.
Research interests.
Cryptography, law, technology policy, privacy, security, game theory.
Preprints.
