Kendrick Kay's page

I am a postdoctoral researcher at Stanford University under the direction of Professor Brian Wandell, investigating the computational properties of extrastriate cortex. My research interests include shape representation in the visual system, functional magnetic resonance imaging methods, computational and theoretical neuroscience, statistical and machine learning methods, and brain-machine interfaces.

Here is my CV.

Here is my blog on statistical analyses in MATLAB.
