Research Interests

I am interested in the interplay between statistical mechanics, symbolic dynamics, probability theory, ergodic theory, combinatorics and computation theory.  Here are some questions and topics (very much out-of-date) I think about.

50 Years of Random Cluster Model (Leiden, June 2019)
Symbolic Dynamical Systems (Oaxaca, May 2019)
Mark Kac seminar (Utrecht, May 2019)
Topics in Mathematical Physics (São Paulo, July 2018)
Mathematical Physics of Non-periodic Structures (Będlewo, July 2018)
Current Trends in Dynamical Systems (Vancouver, July–August 2017)
