I'm a student at University of Alabama at Birmingham working on a PhD in computer science with Thomas Gilray. We're working on tunable static analysis. We created an AAM analysis visualizer to help us as we start analyzing delimited continuations.

As a side project I've worked with Rust's type-level system. I've learned to do computation with traits, and to set up simple type functions and semantic rules.

I received my master's degree through the Programming Languages and Verification group at CU Boulder, advised by Matthew Hammer. We worked together on incremental computation with Adapton in Rust.

In undergrad I worked with Adapton in OCaml at UMD's PLUM lab. I also worked on a few data visualizations in javascript.
