I’m currently a graduate student at Northeastern University studying programming languages and type systems with Amal Ahmed. Previously, I helped start and run a worker-owned software contracting company, Position Development. I studied math and computer science undergrad at Brown University where I worked with Shriram Krishnamurthi. I’m interested in programming languages, education, and leftist politics. This is my personal website.

The easiest way to get in touch is via email: [email protected]. Note that if you have another email address for me, it will probably work as well. I’m currently located in Somerville, MA.
