WORK HISTORY:

March 1978 August 1979, worked as a software engineer at the Large Computer Group of Digital Equipment Corp. in Marlboro, MA.

September 1979 October 1984. Graduate student at the Department of Physiology, Uniformed Services University of the Health Sciences (USUHS) in Bethesda, MD.

November 1984 August 1986. Post doctoral position in the department of Medicine, USUHS. Project was on myocardial and coronary involvement in hemorrhagic shock. Extensive experience in cardio thoracic surgery and in maintenance of animals with chronically implanted cardiac instrumentation. Designed, built and validated a ventricular impedance catheter superior to commercially existing units, and utilizing new principles of operation.

September 1986 1988, Physiologist, and 1988 to August 1996, Staff Fellow, in the Laboratory of Neuropsychology, NIMH. Recording from single units and small numbers of single units in awake behaving primates in several areas of the visual system.

September 1996 - Present: Assistant/Associate professor in the Department of Physiological Optics/Vision Sciences, School of Optometry, in the University of Alabama at Birmingham. Work on single- and multiple- unit recordings in the visual system of awake monkeys.

Research/Clinical Interest
Title
Information Processing in the Central Nervous System
Description
I am primarily interested in how information is processed and transmitted in the brain, mostly but not exclusively in the cortical visual system. I am especially interested in how temporal dynamics may be involved. The techniques that I use range from recordings from single and small groups of single neurons in the visual system of nonhuman primates, to retinal ganglion cells, electroencepaholographic recordings in human subjects, and mathematical modeling.
