Ph.D., 2009, Rockefeller University
My research focuses on the elucidating of the layers of regulation that govern cellular functions, particularly those relevant to metabolic disease. I am currently investigating transcriptional changes induced by loss of the Tsc genes and am exploring the role of mTOR repression in ameliorating the diabetic phenotype.
