John R. Hetling

John R. Hetling is an Associate Professor at the University of Illinois at Chicago in the departments of Bioengineering[1] and Ophthalmology and Visual Sciences [2]. He is also the Director of Undergraduate Studies for the Department of Bioengineering and the Director of the Laboratory of Neurotronic Communication [3] at UIC. He is a world leader and expert on neural prosthesis of the neural retina and testing electrical stimulation devices in the retina. His researh group has pioneered the use of intraretinal electroretinography (ERG) as a means of directly testing the physiology of the neural retina. His specific research interests focus on the extraction of information from complex or inaccessible biological systems, specifically as it relates to phototransduction in living animals, and large pattern-generating neural networks.[4]

Biography

After graduating from Bates College in 1989 with a degree in Biology, Hetling worked for two years in the neuroelectrophysiology laboratory of Patsy Dickinson at Bowdoin College studying rhythmic motor pattern generation. He then began his PhD at UIC in 1991 in the laboratory of David R. Pepperberg, which he completed in 1998. Following his PhD he did a postdoctoral fellowship in the Department of Ophthalmology and Visual Sciences at UIC before being named a Visiting Assistant Professor in the Department of Bioengineering also at UIC. Hetling began his tenure track faculty position as an Assistant Professor at UIC in 1999. [5]
