I'm a number theorist, and, in Dyson's classification, a frog. I enjoy simple-seeming questions that lead to a richness of structure. Areas of interest include Kleinian groups, elliptic curves, algebraic divisibility sequences, Diophantine geometry, arithmetic dynamics, quadratic and hermitian forms, hyperbolic geometry, cryptography and game theory. I enjoy problems that involve experimental mathematics, using a computer.
