Assistant Professor of Psychological and Brain Sciences

My research mainly focuses on understanding adaptive decision making and learning. Specifically, I am interested in understanding neural mechanisms underlying these processes and exploring how computations required for these processes are performed by neuronal elements in the brain.   We use detailed computational modeling at different levels (synaptic, cellular, and network), as well as psychophysics and behavioral studies in humans, to look for feasible mechanisms that account for both behavioral and neural data. The ultimate goal is to bridge the gap between cognitive and neuronal processes, and further explain behavioral laws in terms of biophysical parameters and constraints.
