Marek Petrik

I am an Assistant Professor in the Department of Computer Science at the University of New Hampshire. Before UNH, I was a Research Staff Member at the IBM’s T. J. Watson Research Center in Yorktown, NY. I received my Ph.D. from University of Massachusetts Amherst in 2010. My advisor was: Shlomo Zilberstein.

I am also a member of the artificial intelligence research group at UNH.

Research Interests

I am interested in robust data-driven decision making and in particular in reinforcement learning with limited data sets, risk aversion, and Bayesian models of uncertainty. My application areas include natural resource management, agriculture, and space physics. I had previously worked on applications in precision agriculture, natural resources, renewable energy management, supply chains, advertising, and others.
