Overview
We study circuits for cognition. Using a combination of neurophysiology and biomedical engineering, we focus on the interaction between brain areas during visual perception, decision-making, and motor planning. Specific projects include the role of frontal cortex in metacognition, the role of cerebellar-frontal circuits in action timing, the neural basis of "good enough" decision-making (satisficing), and the neural mechanisms of transcranial magnetic stimulation (TMS).

Selective encoding of priors for flexible categorization but not Bayesian inference in the frontal eye field.
Journal Article The Journal of neuroscience : the official journal of the Society for Neuroscience · May 2026 Expectations or prior beliefs about the world modulate sensory processing at the behavioral and neural levels. Bayesian models predict that such priors compensate for input uncertainty to optimize sensory judgments. Although Bayesian behavior is prevalent ...

Journal Article Cell Rep Methods · March 23, 2026 Understanding the structure-function relationships across neurons is challenging, particularly when circuits are composed of dozens of distinct cell types. We refined an approach, called "projection targeting with phototagging", that allows simultaneous el ... Full text Link to item CiteRecent Grants
