Current Research Activities
We have two major focuses:
1. Characterization of physiological unfolded protein response in mammals;
2. Elucidation of the role of Inflammatory response in obesity and diabetes. 

We use biochemical, genetic, immunological and high throughput approaches to study these fundamental questions.  For more information, please visit our lab website.


Biographical Statement
Ling Qi Obtained his B.S. in Microbiology with honor in 1997 from Fudan University, Shanghai, China and his Ph.D. in Immunology from University of Maryland in 2001.  He then finished two postdoctoral fellowships with Dr. Carol Greider at the Johns Hopkins University (2001-2004) and Dr. Marc Montminy at the Salk Institute (2004-2007).  He was funded by the Leukemia and Lymphoma Society (2002-2005) and the Juvenile Diabetes Research Foundation (2005-2007).  His work has been published in Science, Nature, Nature Cell Biology and Cell Metabolism.  He joined the faculty of Division of Nutritional Sciences at Cornell University in August of 2007.  Currently, his lab is funded by NIH, American Diabetes Association, American Federation for Aging Research and Cornell VERGE.
