From 2021 to 2024, I was a Senior Privacy Engineer at the Wikimedia Foundation, where I worked on large-scale implementations of differential privacy, high-level policy, and (sometimes) AI.<\/p>\n\n\n\n

I hold a B.S. in Computer Science, and have held technical internships at the New York Times, New Hampshire Democratic Party, and as a researcher at Brown University.

Relevant coursework includes: Computer Systems, Computer Systems Security, Cryptography, Theory of Computation, Distributed Computer Systems, Deep Learning, Algorithms for the People.

Here are my Github<\/a> and Gitlab<\/a> profiles. Any code that I still have access to can be made available on request.<\/p>\n\n\n\n
