Bio
I study the neural mechanisms of visual attention, with a particular focus on attentional control in the prefrontal cortex. My research combines electrophysiological recordings, eye-tracking data, and computational methods to examine how neural circuit dynamics support visual processing and attentional selection. More broadly, I am interested in how brain systems transform sensory information into perception, cognition, and goal-directed behavior.
