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

Teaching

I am not teaching this quarter.
