Biography

My interest is in studying how the brain codes and computes information between a sensory input
and a behavioral output. These studies incorporate three main techniques: 1) recording from
single or small populations of neurons in anesthetized animals responding to visual stimuli, 2)
imaging of neuronal activity using intrinsic optical signals, voltage-sensitive dyes, and fMRI
techniques, and 3) recording and imaging from awake monkeys trained to perform cognitive
tasks.
