I am interested in problems that combine number theory, geometry, combinatorics, and algebra. Though I have worked in graph theory and lattice-based cryptography, the most consistent theme of my work is that of curves over finite fields. These curves are fascinating because they bridge the finite and the infinite, are amenable to both computational exploration and geometric intuition, and present a surprisingly wide variety of intriguing questions.
