Synopsis Of Research:

Using psychophysical experiments, I try to decipher the visual strategies that observers use to accomplish tasks like judging color and shape of 3-D objects and the state of materials in real situations. I then try to see how the massively parallel processing of visual primitives by the cortex can be exploited to build simple neural models of these strategies. Finally, I collaborate on striate and extra-striate cortical electrophysiology to ground these models in neural reality.
