I am an Assistant Professor in the Department of Mathematics at Bucknell University. I work in dynamical systems and am currently interested in thermodynamic formalism as well as problems related to multidimensional symbolic dynamics. My CV is available here.

Teaching

In Fall 2014 I will be teaching Math 201 (Calculus I) and Math 311 (Number Theory). Course information and assignments will be posted on Moodle.
