Dynamics at the University of Maryland is distinguished by its quality, breadth and activity. The Chaos Group spans several departments and units on campus. In this website you will find information regarding the Mathematics Department.



  • Joe Auslander (Emeritus): topological dynamics
  • Ken Berg (Emeritus): ergodic theory, topological dynamics
  • Mike Boyle: ergodic theory, symbolic dynamics, topological dynamics
  • Michael Brin (Emeritus): smooth dynamics, smooth ergodic theory
  • Dmitry Dolgopyat: conservative dynamics, probability, smooth dynamics, smooth ergodic theory, stochastic dynamics
  • Giovanni Forni: conservative dynamics, parabolic dynamics, smooth dynamics, smooth ergodic theory, Teichmueller dynamics
  • Brian Hunt: chaotic dynamics, smooth dynamics
  • Michael Jakobson: one dimensional dynamics, smooth ergodic theory, stochastic dynamics
  • Vadim Kaloshin: Arnold diffusion, celestial mechanics, hamiltonian PDEs, KAM theory, smooth dynamics, stochastic dynamics
  • Jim Yorke: applied mathematics, chaotic dynamics, smooth dynamics 

Dynamics at UMD is intrinsically wide ranging, and even within the mathematics department the interest area goes beyond the above list, for example in the work of the geometers William Goldman (ergodic theory on moduli spaces), Karin Melnick (group actions on manifolds), and Scott Wolpert (dynamics of the Weil-Petersson flow).


Postdoctoral fellows and visitors

  • Guan Huang: Hamiltonian PDEs
  • Pablo Roldan: celestial mechanics
  • Kelly Yancey: abstract ergodic theory, topological dynamics



The Dynamics group at UMD organizes the following activities.

Dynamics Seminar

The meetings occur on Thursdays from 2:10--4:10pm, and are divided into two parts: the first one is an introduction of the topic that is accessible to graduate students, and the second is a discussion/explanation of the (idea of the) proof of the main result. After the seminar there is a social hour that offers drinks and snakcs.

RIT on Dynamics

The Reserach Interaction Team on Dynamics meets on Mondays at 3--4:30pm. The goal of the RIT is to introduce basic techniques and open problems in the different fields of dynamics.

Applied Dynamics Seminar

The seminar meets on Thursdays at 12:30pm. It brings in a range of visitors from labs, agencies and other universities in the region, and typically features a "pizza dynamics" framework: two twenty minute talks along with lunch.

Maryland-Penn State Dynamics Conference

Beginning in Fall 1991, the dynamics groups of the University of Maryland and Pennsylvania State University have jointly sponsored two annual three and half day meetings in dynamical systems and related topics: a spring meeting here in College Park, and a fall meeting in State College. These meetings, though primarily regional, also attract participants outside the region and the country. Along with talks of prominent mathematicians, the conferences always include several short talks by graduate students. 

The Michael Brin Chair in Mathematics

Vadim Kaloshin occupies the Michael Brin Chair in Mathematics. 
This position controls substantial discretionary funds, and is permanent as long as the appointed person remains a professor of mathematics at Maryland. The Chair also sponsors Brin Postdoctoral Fellows. 


The Michael Brin Prize in Dynamical Systems

This is an international prize awarded by an international panel of dynamics luminaries. It recognizes mathematicians who have made substantial impact at an early stage of their careers.

The 2008 Michael Brin Prize in Dynamical Systems was awarded to Giovanni Forni.

The 2009 Michael Brin Prize in Dynamical Systems was awarded to Dmitry Dolgopyat.

The 2011 Michael Brin Prize in Dynamical Systems was awarded to Artur Avila.

The 2013 Michael Brin Prize in Dynamical Systems was awarded to Omri Sarig.
