I am primarily interested in mathematical and computational finance. I have enjoyed working on free boundary problems for American options and the melting of ice, and functional expansions/occupied processes to understand the role of path dependence in finance. Broadly speaking, I am seeking out beauty in mathematical objects and financial instruments.
