My name is Leah Namisa Rosenbloom and my pronouns are they/them.

I am currently a PhD Candidate at Brown University studying the intersection of cryptography and grassroots organizing, privacy and security for marginalized communities, abolitionist teaching, and zero-knowledge proof systems. My advisors are Anna Lysyanskaya and Seny Kamara.

Other professional interests include computer science education, the surveillance of social movements, anonymous networks, election security, password security, and the intersection of technology and the criminal justice system.

Previously I was a math teacher of amazing 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.

I am also a manga artist and arcade game enthusiast.
