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.
In Spring 2018 I am teaching Math 212 (Differential Equations) and Math 303 (Probability). Information for these courses is available on Moodle.
