Welcome!
I am a fourth-year PhD student in the Department of Computer Science and Engineering at the University of Michigan. My advisor is Professor Max New. In May 2021, I obtained my MSE in Computer and Information Science from the University of Pennsylvania. During my time at Penn, I was fortunate to work with Professor Stephanie Weirich on the hs-to-coq tool as part of an independent study. Previously, I attended Rutgers University New Brunswick, where I studied Computer Science and Math.
My research interests are primarily in the theoretical study of programming languages. I am especially interested in applying tools from mathematics (e.g., category theory) to build and analyze programming languages. More broadly, I am also interested in theoretical areas of computer science as a whole, including Theory A topics (e.g., computational complexity theory).

Research Projects
- Denotational Semantics of Gradual Typing using Synthetic Guarded Domain Theory: In this work, we develop a denotational semantics for a simple gradually-typed language using the tools of synthetic guarded domain theory. The result is a reusable and compositional semantic framework that we expect to be capable of extending to languages with advanced recursive features including higher-order store. Future work will seek to extend the framework to accommodate these features. Our work builds on prior denotational models of gradual typing, but in place of classical domain theory, we use guarded type theory.
- Gradual Typing for Effect Handlers: I contributed to proving metatheoretic properties of GrEff, a proof-of-concept gradually-typed programming language with effects. The language is designed to model the situation where one would like to retrofit an effect typing system onto an existing programming language with effects.
- Invariants with
hs-to-coq(Jan 2020-Sept 2020): I worked on modifying thehs-to-coqtool to support automatically generating proof obligations for datatype invariants.
