Biography: 

James A. Reggia is a professor emeritus of computer science with joint appointments in UMIACS and in the Department of Neurology at the University of Maryland, Baltimore.

His research interests span neural computation, artificial intelligence, genetic programming, and artificial life.

Reggia has authored more than 200 refereed journal and conference papers in these areas. Recently he has focused on developing new methods for creating large-scale integrated neuro-computational systems as a basis or machine intelligence and neurocognitive modeling. This work has included modeling of specific cortical regions for visual and language processing, and modeling of basic cortical mechanisms, such as self-organizing map formation, learning to process temporal sequences, emergence of hemispheric asymmetries and specialization, and working memory.

His past work has been funded by DARPA, ONR, NSF, NIH, and multiple industry sources. He routinely teaches computer science graduate courses in neural computation, artificial intelligence, machine learning, evolutionary computation, and artificial life.

Reggia holds a doctorate in computer science from the University of Maryland and an M.D. in clinical neurology.
