 CV: html pdf

I study how the brain learns what things are good and what things are bad, and how it uses this knowledge to banish the bad things and gather the good things! I believe that learning about the world is not simply a passive process of parameter estimation and error-reduction, but an active delight of exploration and discovery. Why else be a scientist?
