Norman R. Harris, PhD

Professor and Chair of Molecular and Cellular Physiology
Bachelor of Science (1987) - Tennessee Technological University

Dr. Randa Eshaq, Post-Doctoral Fellow, was recently awarded the 2019 Allied Health Teaching Award. The award is presented annual to one student and one faculty/post-doc course instructor.


My research career has focused on the physiology and pathophysiology of the microcirculation, and in recent years, much of our work has been an investigation of the retinal microvascular complications of diabetes.  Our lab is currently funded with an NIH R01 entitled “Loss of the retinal glycocalyx in diabetes”, and we also have ongoing projects related to other retinal pathologies.

Techniques that we use in the laboratory include intravital microscopy, measurement of microvascular flow, computerized video analysis of microscope images, immunostaining of tissue sections, culturing of retinal microvascular endothelial cells, and western blotting.

Below is one of our images of the retinal vasculature (in green) and neuronal nuclei (in red).
