Brief Profile:

Dr. Reddy obtained his PhD in Biochemistry (1996) from Osmania University. He did postdoctoral trainings at the Indian Institute of Science, Bangalore and the Case Western Reserve University (USA). He joined the institute in 2000 and currently heads the Department of Ocular Biochemistry. He has been a Visiting Scientist in 2003, 2005 and 2007 at the University of Michigan and in 2014 at the Cincinnati Children’s Hospital and Medical Center.
He is a recipient of

  • ICMR-Basanti Devi Amir Chand Prize (2010)
  • Scopus India Young Scientist Award (2008)
  • RPB-International Research Scholars Award (2007)
  • ICMR-Excellent Research Output Award (2006)
  • ICMR-Dr. VN. Patwardhan Prize (2002), and
  • Nutrition Society of India (NSI) Young Scientist Award.

Dr. Reddy is a Fellow of

  • the National Academy of Sciences, India and
  • the AP Akademi of Sciences,

Dr. Reddy’s research is focused on nutrigenomics of age-related diseases, particularly complications of diabetes and obesity. His studies discovered a role for micronutrients in the development of diabetic complications. Importantly, he has revealed how deficiency of some micronutrients can influence the molecular processes and provided a basis for micronutrient involvement in diabetic complications using animal models. Also identified mutations in some genes that cause age-related diseases such as cataract and retinal degeneration. His studies are aimed at developing suitable animal models for studying the disease biology of diabetes, prediabetes and obesity associated complications and also to understand the role of nutrition. Dr. Reddy described age-related eye diseases- retinal degeneration and cataract in a spontaneous obese rat model. His pioneering work on involvement protein glycation and aldo-keto reductases under chronic hyperglycemia, paved the way for exploring functional foods molecules as aldose reductase inhibitors (ARI) and antiglycating agents (AGA). Further, isolated and characterized novel compounds from functional foods as ARI and AGA for combating diabetic complications. Dr. Reddy has provided new insights into the structure, function and expression of small heat shock proteins under hyperglycemic conditions and their modulation by nutritional factors. So far ten students have obtained PhD under his supervision. He has published over 110 research papers in peer-reviewed scientific journals and has two patents to his credit.
