I'm a PhD candidate in computer science at Brown University. I work on privacy and applied cryptography, advised by Seny Kamara. Broadly, my work focuses on designing usable cryptographic solutions. I also work with Elissa Redmiles and others on research that investigates image-based sexual abuse. My work is supported by the NSF Graduate Research Fellowship. email | scholar | twitter
