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.

Professional Updates:

June 2026: Alexis Korb and I will be hosting a small workshop on teaching-oriented academic jobs during the free afternoon at CRYPTO this year! If you're interested in learning more about these types of positions (either for yourself or your students), feel free to show up! We're also very interested in getting in touch with cryptographers in teaching-heavy jobs (e.g., teaching faculty or those at liberal arts colleges) that we haven't already met.
April 2026: The Dagstuhl seminar on Privacy-Preserving Authentication was absolutely amazing :) :) :) Can you find me in the photos? (Hint: some of the attendees are very tall...)
April 2026: Congratulations to Madiha Zahrah Choksi on being awarded a DSI Postdoc Fellowship!! So excited to be one of her co-mentors when she joins in the fall!!!
Mar 2026: I can't believe it either, but I'm on the IACR Schools Committee!! Very excited to evaluate proposals for cryptology schools :)
Jan 2026: I guess I'm on the steering committee for CFAIL now? Let's all continue to fail better ٩(^ᗜ^ )و
Dec 2025: Woah, I'm now a member of the DSI at Columbia (affiliated with the Cybersecurity Center)!
Aug 2025: Woohoo! Our paper on signature functionalities was accepted to TCC 2025! Aarhus, here we come!
May 2025: Yay! Our paper on multi-holder anonymous credentials was accepted to CRYPTO 2025! See you all there!
Spring 2025: I'M GOING TO BE A PROFESSOR!! I'm so so so excited to announce starting July 2025, I'll be an Assistant Professor of Computer Science at Barnard College, Columbia University!!
Fall 2024: I'm planning to go on the job market! Wish me luck :)


Misc

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

I generally try to stay on top of emails, but somethings things get lost in my inbox (especially while traveling). If you don't hear back within a week, feel free to send a follow-up. I kindly request you refrain from overuse of generative AI in emails to me.

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).
