Research Interests
I was trained as a physiological psychologist and the enduring theme of my research has been the relationship between brain activity and human experience and behavior. Throughout my career, I have employed electrophysiological and psychophysical techniques to address these questions. Much of my work has been carried out in the area of visual perception and human performance, but I have also developed expertise in auditory, vestibular, and cognitive processes. Recent and ongoing research projects include:

I maintain active research collaborations with the Neuroscience Center of Excellence at the Louisiana State University Medical Center and the National Biodynamics Laboratory in the College of Engineering at UNO.
