Research

We use behavior, computational modeling, electrophysiology, neuroimaging, and noninvasive neuromodulation techniques to understand the large-scale causal mechanisms of perception and cognition in the healthy adult brain, and how these mechanisms go awry in normal and pathological aging, and psychiatric illnesses, such as schizophrenia and obsessive-compulsive disorder. We also build unique neuromodulation protocols, grounded in fundamental science, to control components of perception and cognition in healthy individuals and to protect or restore abilities in aging and clinical populations.

Emotion-Cognition Interactions

Using behavior, mega-analysis, electrophysiology and noninvasive neuromodulation, we are probing the mechanisms for how episodic memory prioritizes experiences that hold motivational significance or emotional salience.

Working Memory & Executive Function

Using behavior, electrophysiology, neuroimaging, machine-learning decoding, and noninvasive neuromodulation, we are working to understand the neurocomputational mechanisms that govern various memory and executive processes involved in encoding, maintenance, gating, shielding, deletion, and retrieval of information important for decision-making and goal-directed action.

Computational Memory

Using behavior, modeling, eye tracking, electrophysiology, and noninvasive neuromodulation, we are trying to uncover the computational processes underlying memory for complex objects and scenes.

Perception & Consciousness

Using psychophysics, electrophysiology, neuroimaging, and noninvasive neuromodulation, we are working to characterize the causal neural substrate of conscious and non-conscious visual perceptual experience.

Mental Illness

Using behavior, electrophysiology and noninvasive neuromodulation, we are aiming to identify and repair aberrant neurocomputational mechanisms underlying components of cognitive dysfunction in mental illnesses such as schizophrenia and obsessive-compulsive disorder.

Aging & Alzheimer’s Disease

Using behavior, electrophysiology, neuroimaging, and noninvasive neuromodulation, we are seeking to better understand and rescue memory and executive processes in healthy and pathological aging by synchronizing neural population activity in a rapid and sustainable fashion.
