Eysa Lee
Email: eysa_lee @ brown.eduI am a Postdoctoral Research Associate in the Data Science Institute (DSI) at Brown University under the mentorship of Anna Lysyanskaya.
I completed my PhD at Northeastern University in 2023, where I was advised by abhi shelat.
My research interests are in cryptography, and specifically signatures and multi-party computation.
For Summer 2018, I visited Bar-Ilan University for a summer program on applied MPC and implementation.
For Summer 2019, I worked with Peter Rindal as an intern at Visa Research in Palo Alto.
For Summer 2022, I interned with an applied research team (FLARE) at JP Morgan in New York City.
