Dr. Gardiner spent two years after his PhD (1976 to 1978) as a USPHS Postdoctoral Fellow in the laboratory of Dr. V. Edgerton, UCLA.
My main research interest is in the adaptations that occur in the nervous and neuromuscular systems as a result of increased and decreased physical activity, aging, spinal cord injury, stroke, obesity and type 2 diabetes. Adaptations that are of interest include electrophysiology, morphology, and gene expression.
