On March 7 I am giving the Applied Algebra seminar at Berkeley.

On April 1 I am giving the Galois seminar at Penn.

I will be speaking at the Sixth Annual Upstate NY Number Theory Conference, April 30-May 1.

From May 16-20 I will be attending the workshop on The Galois Theory of Orbits in Arithmetic Dynamics at AIM in San Jose, CA.

In Fall 2016 I will be joining the math department at Texas A&M as an Instructional Assistant Professor.

My research interests are primarily in number theory and algebraic geometry, and more specifically in arithmetic dynamics. I study algebraic, arithmetic, and combinatorial properties of dynamical systems, such as ramification of primes in fields generated by preimages of a given point under a rational map, or how the number of periodic points of a map changes as the underlying field varies. I am also very interested in the applications of finite automata to algebra and number theory.
