I'm an applied cryptographer and usable security/privacy researcher. I’m currently a Postdoctoral Fellow in computer science at Georgetown University where I work closely with Elissa Redmiles. I'm also a Fritz Fellow within Georgetown's Initiative for Technology and Society. Last December, I completed my PhD in computer science with a focus on applied cryptography at Brown University where I was advised by Seny Kamara. Currently, my research centers more on projects addressing image-based sexual abuse. I also co-organize the Re-Imagining Cryptography and Privacy (ReCAP) Workshop, alongside Alishah Chator and Leah Namisa Rosenbloom. email | google scholar | twitter
