I was originally trained as an electrical engineer, and worked in industry for a time, but then moved on to physiology. I am first and foremost a systems neuroscientist: I am interested in how information is processed and transmitted in the nervous system, not so much the details of specific genes and ion channels etc. I worked at the National Institutes of Mental Health (NIMH) before moving to the UAB School of Optometry in 1996, where I remain to this day. I have applied this interest to the visual system, exploring visual cortical neuronal dynamics and, more recently, dynamics in the retina. Finally, I have a long-standing interest in science fiction, having authored the popular "Old Guy" series of cybertank novels (available on Amazon!).
My current primary interest is in the neural circuitry that actively controls eye growth during infancy and childhood. We know that the retina uses visual cues to control eye growth, but we still don't know what these cues are, or how they are integrated, or what neural circuits are involved. This is of interest both scientifically and clinically, because it is the failure of this system in modern civilization that is leading to our current epidemic of myopia. I am also involved in collaborative efforts looking at cortical brain dynamics and schizophrenia.
