Brief Profile

PhD in Biochemistry (Osmania University); Postdoctoral research at the Indian Institute of Science, Bengaluru and Case Western Reserve University, Cleveland- USA. Worked as ICMR, DBT and DHR Fellow at the University of Michigan (2005 and 2007) and Cincinnati Children’s Hospital Medical Center (2014), respectively.
His research is devoted to exploring on diverse facets of human nutrition ranging from deriving nutrient requirements to evaluating nutrient deficiencies, understanding the impact of food/nutrition on chronic diseases, and formulating dietary intervention strategies. He also delves into age-related disorders, with a particular focus on unraveling micronutrient-mediated molecular processes such as proteostasis and fibrotic mechanisms. Moreover, he investigates protective effects of functional foods and novel bioactive molecules. He reported the prevalence of micronutrient deficiencies and identified the factors contributing to inadequate micronutrient intakes. A major aspect of his research involves studying protein modifications by non-enzymatic glycation and aldo-keto reductases under conditions of chronic hyperglycemia. This research led to the discovery of novel bioactive molecules from functional foods, culminating in the development of functional food formulations targeting diabetes complications.  Additionally, his research sheds light on protein quality control mechanisms revealing insight into impaired ubiquitin-proteasome system, ER stress, and autophagy in conditions such as muscle atrophy, retinal degeneration, and neuronal cell death associated with obesity and diabetes.
