My research is in computer security, with recent topics including interpersonal technology abuse, applied and theoretical cryptography, and authentication.

Starting January 2026, I am at the University of Toronto and on leave from Cornell University. As such, I will not be taking new PhD students at Cornell for the foreseeable future.

I previously worked part time at Cloudflare Research.

I'm part of a research team working on computer security and privacy issues in the context of intimate partner violence. This led us to found the Clinic to End Tech Abuse.
