Biography

 

Dr. Dao-Qi Zhang received his Ph.D. in neurobiology from the Institute of Physiology, Chinese Academy of Sciences in 1997. He completed his post-doctoral training within the Department of Physiology at the University of Kentucky. Before he joined the Eye Research Institute in 2010, he served as Research Assistant Professor in the Department of Biological Sciences at Vanderbilt University. Dr. Zhang has received a fellowship from the Association for Research in Vision and Ophthalmology and Alcon Laboratories, as well as research awards from the National Eye Institute and the Midwest Eye-Banks. 

 

Research

 

Dr. Zhang’s research focuses on understanding the regulation of dopamine release in the vertebrate retina, a simple and accessible model of the CNS. Retinal dopamine acts as a neurotransmitter and plays vital roles in modulating retinal circuits, synchronizing the retinal clock, and influencing eye growth. As a result, dopamine deficiency in neurodegenerative diseases such as diabetic retinopathy, retinopathy of prematurity, and Parkinson’s disease leads to a number of visual defects affecting the spatial and temporal vision, as well as absolute visual sensitivity. However, the mechanisms responsible for regulating dopamine release are not well understood. The broad objective of Dr. Zhang’s laboratory is to determine how retinal dopaminergic neuron activity is regulated by environmental light and the circadian biological clock, and how it is altered in a mouse model of retinopathy of prematurity. With further understanding of these mechanisms, we will be able to better comprehend the underlying problems of these diseases and develop an effective treatment for them. Dr. Zhang’s laboratory utilizes a multidisciplinary approach that includes molecular, pharmacological, biochemical, optical imaging, and electrophysiological techniques. The research is currently supported by the National Eye Institute (R01EY022640).
