Research Area:

Every life is a series of decisions. Even a bee needs to balance the rewards a flower provides and the uncertainty that it may contain nothing. Following a decision-theoretic approach, I study a wide range of problems in perception, action, and cognition. The central question is: How does the brain represent and compute uncertainty in decision-making? I use psychophysics and computational modeling, and will integrate brain-imaging techniques, to seek an understanding from behavior, to computational algorithm, to neural basis.
