¾ÅÉ«ÊÓƵ

I am a professor of mathematics at T¾ÅÉ«ÊÓƵ and also a member of the doctoral faculty at the CUNY Graduate Center. From 2012 to 2016 and 2021 to 2022 I served as mathematics department chair at The City College. In addition to teaching, I enjoy mentoring students doing research and independent study projects.

After my PhD at the Technical University of Munich (1999), I taught at Indiana University, Bloomington from 1999 through 2001, and spend the year of 2002 at the Technical University of Lisbon. In the Spring of 2003 I joined Wichita State University in Kansas where I stayed until Spring 2010. Finally, in Fall of 2010, I arrived at the City College.

I studied mathematics and physics at the University of Munich in Germany. I then received my PhD at the Technical University of Munich (1999)

My research is in the area of ergodic theory and dynamical systems. In particular, I am working on geometric, ergodic- and dimension theoretical aspects of smooth and symbolic dynamical systems. This includes the dynamics on real manifolds (Axiom A, non- uniformly hyperbolic and parabolic systems), shift spaces as well as on one- and higher dimensional complex spaces. Recent research interests include the existence problem of zero-temperature limits and of measures of maximal dimension, the computability of dynamically defined objects such as rotation sets, residual entropy and zero-temperature measures, and the application of the thermodynamic formalism to evolutionary biology. My research is supported by a Collaboration Grant for Mathematicians from the Simons Foundation (#637594 to Christian Wolf).
