Biography

Dr. Zhengping Yi is an Associate Professor of Pharmaceutical Sciences. Dr. Yi joins Wayne State University from the School of Life Sciences at Arizona State University where he served as Research Assistant Professor since 2005 and was Director of the Proteomics Research Laboratory. Dr. Yi earned degrees from Nanjing University in Chemistry, investigating molecule-molecule interactions, culminating in his PhD in 2000. His postdoctoral research examined protein biochemistry at Purdue University and proteomics and diabetes at the University of Texas Health Sciences Center, San Antonio. His current research, funded by NIH and American Diabetes Association, explores insulin signaling, insulin resistance, and type 2 diabetes, focusing on the role of novel protein-protein interactions and phosphorylation in aberrant cell signaling.

Primary Research Interest

Insulin resistance lies at the base of the array of diseases or pre-disease conditions known as the Metabolic Syndrome, including obesity, dyslipidemia, hypertension, cardiovascular disease, type 2 diabetes mellitus, and some cancers. Dr. Yi’s research focuses on a better understanding of the basic biology of insulin signaling and the etiology of insulin resistance. Dr. Yi and his group are using a combination of clinical, biological, and proteomic approaches to better comprehend insulin signaling and the associated problems that occur with obesity and T2D. Studying insulin signaling in humans is challenging. Dr. Yi’s laboratory has developed state-of-the-art techniques that can be used to better define and understand the effect of insulin in key metabolic tissues in humans such as skeletal muscle. These approaches are useful models for studying cell signaling pathways in general, and especially their regulation by protein phosphorylation and protein-protein interactions.

 

In addition to directing his independent laboratory working on insulin signaling both in vitro and in vivo, Dr. Yi also directs the Proteomics Research Laboratory in the College of Pharmacy. Proteomics offers the capability to simultaneously quantify multiple proteins, protein-protein interactions, and protein phosphorylation, providing a better picture of complex protein networks.
