Ph.D. 2001 (Illinois at Urbana-Champaign)

My primary scientific interest concerns the cognitive neuroscience of cognitive control and decision making. I am particularly interested in how the brain selects and sustains extended sequences of behavior, for example, how do we decide to jog up a steep mountain and then actually follow through with this decision rather than to stay at home and watch TV? My research points to anterior cingulate cortex and the midbrain dopamine system as a critical neural interface supporting such behavior, which I try to understand using a formal theoretical approach called Hierarchical Reinforcement Learning. Other related interests concern the neural mechanisms of substance dependence and attention-deficit hyperactivity disorder, both disorders of cognitive control and reward processing. I have also developed recent interests in spatial processing and navigation (parahippocampus), attention (locus coeruleus) and continuous motor control (posterior parietal cortex). To get at these issues I follow a "converging methods" approach involving electroencephalography, functional magnetic resonance imaging, genetics and computational modelling.
