I received my bachelors degree in Psychology from the University of Wyoming and my Ph.D. in Experimental Psychology from the University of Florida. My dissertation research was in the area of color vision, specifically looking at color detection and discrimination in individuals with different congenital color vision deficiencies.
I came to APSU in 1992 and my primary teaching responsibilities are General Psychology, Statistics for the Behavioral Sciences, and Sensory Processes.
Personal interests include triathlon, cycling, and motorcycling.
My research interests are in visual perception. Most of my research has had the common thread of having a neuropsychology-slant to them. Past projects have looked at different visual perceptual tasks in individuals with mild to moderate intellectual disability, for example.
Current projects involve collaborating with individuals at Blanchfield Army Community Hospital, to investigate the visual, oculo-motor, and vestibular symptoms associated with mild TBI and imaging brain activity in soldiers with PTSD.

I enjoy designing and implementing experiments in a Matlab environment and then analyzing the data with scripts I write for R. Below is an R Heat Map showing amount of activity (as a Z-score) at 1-30 Hz by Brodmann area for the left and right hemispheres. Click for larger image.
