Biography 

Weiping Han obtained his Ph.D. in Physiology from Cornell University in 1996. He did his postdoctoral work at the University of Pittsburgh and HHMI/UT Southwestern Medical Center in Dallas. In 2003, he was promoted to Research Assistant Professor in the Center for Basic Neuroscience at UT Southwestern Medical Center, where he studied molecular mechanisms of hormone secretion and signaling. In 2005, he moved to Singapore to set up a research program in the Laboratory of Metabolic Medicine (LMM) at Singapore Bioimaging Consortium (SBIC), and was promoted to Research Director / Professor in 2013. Currently he is Deputy Director of SBIC with concurrent appointment as Head of LMM. He is also Research Director at Institute of Molecular and Cell Biology; Professor in the Program in Cardiovascular and Metabolic Disorders, Duke-NUS.

My research aims to understand the molecular basis of diabetes and its complications, to discover and validate targets for drug development, and to develop animal models for evaluation of therapeutic interventions. My lab uses molecular genetics, cell biology, and physiology techniques to analyze genetically modified animals and cell lines. The current major research projects are:

• Molecular control of regulated exocytosis in diabetes development and treatment
• Molecular and cellular mechanisms of adipogenesis and its link to diabetes and other metabolic diseases
• Post-translational modifications and protein functions in hormone secretion and diabetes development
• Molecular link underlying increased risk of cognitive impairments in people with diabetes and other metabolic diseases
