Mathematical Institute, Utrecht University

Teaching

During the spring semester, I am teaching the course Modern Theory of Markov Chains from the SFM program. I also help with the exercise classes of the course Models and Simulation.

In January 2014, I taught a two-week intensive course Introduction to Probability and Statistics to students from the University College. Since Fall 2012, I have also taken care of exercise sessions for a variety of courses including Calculus I (×2), Introduction to Probability and Statistics, Differential Equations, Probability, and Mathematical Techniques II.

Office hours:  Please drop me an email to be sure I am around.

Research Interests

I am interested in the interplays between statistical mechanics, ergodic theory, probability, cellular automata, and computation theory. Here are some questions and topics I think about.
