Research Interests: Understanding the pathogenesis of neuropsychiatric disorders in which neuronal wiring is abnormal, such as mental retardation or schizophrenia, and the first step towards the development of new therapies that would help neuronal rewiring after various insults or after neuronal grafting.

Research Interests:
I am interested in how the brain optimizes cognitive performance under varying circumstances. Anyone who has made a puzzlingly poor decision in a stressful moment realizes that the brain works differently in different contexts. I study the neuromodulatory actions underlying these differences. Neuromodulators such as norepinephrine and dopamine change the way that neurons communicate with each other. My research focuses on how these neuromodulatory systems mediate the impact of factors such as arousal/stress, environmental uncertainty, and motivational salience on learning, attention, and decision making. The central thesis of my work is that these neuromodulators tune cognition adaptively to a range of situations. I study the activity of neuromodulators in healthy human volunteers in several ways that can be grouped into two general approaches: (1) direct manipulation of neuromodulator levels in humans such as with psychopharmacology or neural stimulation; and (2) indirectly inferring neuromodulator activity through biomarkers sensitive to varying neuromodulator levels.
