Yunlei Yang, M.D., Ph.D.

Associate Professor, Department of Medicine (Endocrinology)

Associate Professor, Dominick P. Purpura Department of Neuroscience

Areas of Research: The focus of Dr. Yang's research is on glial and neuronal control of energy metabolism and emotions by using systems neuroscience and metabolism methods, including chemo/optogenetics, electrophysiology, and metabolic assays.

Professional Interests

Dr. Yang is interested in dissecting and manipulating intracellular and intercellular signaling pathways that govern energy metabolism and emotions in normal and obese animals using genetic and systems neuroscience approaches that include cell-type-specific electrophysiology, optogenetics, chemical-genetics, deep-brain measurements of neurochemicals, imaging, and behavior assays. One of the projects in Dr. Yang's laboratory is about synaptic and circuit rewiring in obesity. 

In addition to neuronal regulations of energy metabolism and behaviors, Dr. Yang is also interested in studying the roles played by astrocytes in the control of energy states and emotions in obesity.
