Security/privacy researcher.

I’m currently a Postdoctoral Associate 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 and a Massive Data Institute Fellow at the McCourt School of Public Policy. I completed my PhD in computer science with a focus on applied cryptography at Brown University where I was advised by Seny Kamara.

I'm also part of the Safer Digital Intimacy research collective where we're working on a variety of research projects focused on addressing image-based sexual abuse.

Feel free to send me an email (my signal username is also available upon request)---I'm always happy to connect and talk about research!

I'm currently a member of a multi-stakeholder working group to address image-based sexual abuse. Since 2018, I've been a part of Callisto's cryptography advisory board was a contributor to the cryptographic design of their service, which has been deployed and is available to college students across the U.S.

Alongside Alishah Chator and Leah Namisa Rosenbloom, I co-organize the Re-Imagining Cryptography and Privacy (ReCAP) Workshop. The workshop seeks to explore the ways in which cryptography and privacy intersect with society toward designing, creating, and sustaining technologies that explicitly benefit marginalized communities.
