Student Experience
Division of Academic and Student Engagement
I am interested in the problem of making sequential decisions under uncertainty, in particular when you don't know the system that you're attempting to control. Although simple situations like the multi-armed bandit are well understood, extending this theory to the case where the system has a dynamically evolving state is difficult: optimal solutions become computationally intractable and even principled heuristics from the bandit setting are difficult to apply. I am currently studying this problem using tools from statistical physics and field theory, which might help bring new insight into the "nature" of sequential decision problem.
