Quantum theory applied to problems in chemistry and biochemistry; visual information processing, spatial vision, color vision

Eugene Switkes is a theoretical chemist working in two diverse research areas: applications of basic quantum mechanical theory to problems in organic chemistry and biochemistry, and information processing by the visual system.

His current work in chemistry includes theoretical calculations of the electronic structure of large molecules and formal characterization of nonlinear systems. His research in the area of vision involves experminental and modeling studies of how the human visual system process spatial and chromatic information.

He received UCSC's Distinguished Teaching Award in 1986, the Excellence in Teaching Award from Phi Beta Kappa's Northern California Association in 1983, and the UCSC Committee on Teaching Excellence in Teaching Award in 2003. Switkes is also a member of the Vision Sciences group at UC Berkeley.

Current research areas:
In the human visual system, both chromatic and spatial information are processed by multiple, multi-stage, mechanisms. In addition, patterns defined by color and luminance are, at some levels, processed by differing mechanisms. Switkes's recent research investigates the nature of spatial and chromatic visual processing and the segregation and integration of information across stages and among mechanisms selective for various chromatic dimensions.
