I'm a Computer Science PhD student working in the Computational Logic Center. My advisor is Dr. Aaron Stump. I work with Aaron and others on Cedille. I am interested in programming language theory, logic, and the formalization of mathematics.
My current research revolves around how Cedille's unique feature set (dependent intersections, equality of well-scoped untyped terms, and erased function spaces) can be used to capture and construct many of the ideas in other languages (such as large eliminations, induction-induction, induction-recursion, etc).
