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