Biography

Dr. Liping Huang joined the Western Human Nutrition Research Center in February, 2000. Before joining WHNRC, Dr. Huang worked at the Howard Hughes Medical Institute (HHMI), University of California San Francisco (UCSF) as a post-doctoral associate. Dr. Huang obtained a M.D. degree in Medicine and Public Health at Shanghai Medical University (now Fudan University Shanghai Medical College) in China in 1983 and a Ph.D. degree in molecular biology and virology at University of Iowa College of Medicine in 1995.

Research Interests

Dr. Huang has primarily focused on mammalian zinc transporter proteins and their roles in maintaining body zinc homeostasis, regulating body adiposity, insulin metabolism in pancreatic beta-cells, and insulin resistance in muscle and fat.

Current Research Projects

Current projects focus on the function of zinc transporters in maintaining body zinc homeostasis. Specifically 1) Determine novel functions of zinc related to energy metabolism, insulin resistance in skeletal muscle, and adipose tissue and immune function and 2) Measure and validate novel functional biomarkers of Zn status in response to supplementation of deficient human subjects.

 Research Studies

Our research studies focus on cellular zinc regulation and its links to modulation of body weight gain, adiposity, glucose and insulin homeostasis, and immunity. The goal is to understand the mechanism of zinc action in the body.
