I am a Professor in the Computer Science & Engineering Department at UCSD . This means I can now go barefoot and there is nothing they can do about it! My research is strongly interdisciplinary. It concerns using neural networks as a computational model applied to problems in cognitive science and artificial intelligence, engineering and biology. I have had success using them for such disparate tasks as modeling how children acquire words, studying how lobsters chew, and nonlinear data compression.

My research group, Gary's Unbelievable Research Unit or GURU for short, meets weekly to present our work to one another. I try to give my students mantras, like "One result, one paper" in keeping with the name. But I claim no special knowledge.
I am the Director of the NSF-sponsored Temporal Dynamics of Learning Center.
I am the former Director
of the NSF-sponsored IGERT program
Vision and Learning in Humans and Machines.
The new director is Professor
Virginia de Sa.
...and the Director of the Interdisciplinary PhD Program in Cognitive Science.
...and a co-PI of the Perceptual Expertise Network.
I am part of the Artificial Intelligence Laboratory at UCSD, and sometimes organize the weekly AI Research Group seminar, which meets Mondays in AP&M 4882 at 12:10PM, and includes FREE PIZZA!
I am an Associate Editor for the journal Connection Science . Check it out!
