I am an Assistant Professor of Computer Science at Barnard College, an Affiliate Faculty in the Department of Computer Science at Columbia University, and a member of the Data Science Institute (DSI) at Columbia University.
My research interests are in cryptography, specifically threshold signatures, multi-party computation, and digital credentials.

I completed my PhD in 2023 at Northeastern University advised by abhi shelat and was a Postdoctoral Research Associate in the Data Science Institute (DSI) at Brown University under the mentorship of Anna Lysyanskaya. Before that, I completed my undergraduate studies at The University of Texas at Austin.

Misc

In my spare time, I enjoy doodling, as evident by the Alice and Bob characters in my presentations.

How to pronounce my name:
My name is pronounced like Lisa without the "L" or Isa like "Isa the Iguana" from Dora the Explorer (unfortunately I do not know any cool facts about the rainforest... but I did once disappoint a small child by not being an iguana).
