I am currently a PhD Candidate at Brown University studying the intersection of cryptography and grass-roots organizing, digital privacy for marginalized groups, and zero-knowledge proof systems. Other interests include anonymous networks, voting systems, password security, surveillance of social movements, and the intersection of technology and the criminal justice system. My advisors are Anna Lysyanskaya and Seny Kamara.

Previously I was a math teacher of high school students at The Workshop School, and a technology intern with the Speech, Privacy, and Technology project at the ACLU.

I graudated from the TUteach Program at Temple University with a BS in Math and Computer Science with Teaching, and have an MS from Brown in Computer Science.
