I am a Ph.D. Candidate working under Professor Jeffrey Vaaler at The University of Texas at Austin Department of Mathematics.

I am interested in the solutions of polynomial equations in one variable (the theory of algebraic numbers), and in the algebraic solutions to polynomial equations in several variables (diophantine geometry). I am especially interested in heights, which are real-valued functions that measure the complexity of an algebraic number or an algebraic point on a variety. Most of my research has focused on studying properties of heights over infinite extensions of the rational numbers. This is motivated by applications to diophantine equations, where a powerful tool is to compare height estimates to prove that equations don't have too many solutions.

Likes: heights, diophantine geometry, algebraic number theory, Galois theory, group theory, arithmetic statistics, SAGE, GAP, MAGMA

Papers, etc.
