Educational Background

  • Ph.D. Pennsylvania State University
  • B.S. University of Buffalo, The State University of New York

Research Interests

  • Dynamical systems, ergodic theory, combinatorics. I am interested in thermodynamic formalism (especially of countable state Markov shifts exhibiting transience) and am also involved in projects related to multidimensional symbolic dynamics.
