Research Interests

Cognitive invasive electrophysiology and decision-making

Our brains have evolved to make fast, complex decisions engaging a multitude of brain areas. Using a combination of neuroeconomic tasks and invasive intracranial recordings, I examine how fast, distributed brain activity supports decision-making in the human brain. In addition, I study related cognitive functions (such as learning, memory, or social behavior) and psychiatric conditions characterized by damaged choice behavior (such as addiction, depression and anxiety, and brain lesions).
