Dr. Saras Nair

Dr. S. Nair is a cell and molecular biologist who received her Ph.D. at SUNY at Buffalo and post-doctoral training at Albert Einstein College of Medicine. She has been investigating the molecular and cellular basis of obesity and Type 2 diabetes since 2001, first in Pima Indians at NIDDK, NIH, Phoenix and since 2006 in Mexican Americans and cell culture model systems at UT, Brownsville and currently at UTRGV.
