Current Activities

Currently (Spring 2013) I am an NSF-RTG research assistant (PI Jordan Ellenberg). This summer I will be teaching Math 222.

Research

My research interests are primarily in number theory, computational algebra, and algebraic geometry. Currently I am studying arithmetic dynamics, in particular the dynamics of polynomials and rational functions over finite fields. I am also very interested in the applications of finite automata to algebra and number theory. My advisor is Eric Bach. Here is my CV.

Papers

"The Artin-Mazur Zeta Function of a Lattès Map in Positive Characteristic," in preparation

"On the Number of Distinct Functional Graphs of Affine-Linear Transformations over Finite Fields," with Eric Bach, 2013, to appear in Linear Algebra and Appl.

"Transcendence of The Artin-Mazur Zeta Function for Polynomial Maps of A^1(F_p)," Acta Arith. 156 (2012) no. 3, 293-300

"A Count of Maximal Small Copies in Multibrot Sets," with Rodrigo Pérez, Nonlinearity Vol. 18 No. 5, 2005.

Talks

Here is a video of a talk I gave at the May 2013 BIRS workshop on "The Art of Iterating Rational Functions over Finite Fields" that summarizes some of my research. You can also view the slides from the talk.
