Brief Profile

As a Pathologist and Toxicologist, he collaborates with other colleagues from other Divisions and has undertaken research projects of his own Division also. His areas of interest are (1) Nutrition and Cancer interaction (2) Nutrition & Toxicology

His earlier studies focussed on BMI in human patients with breast cancer and possible correlation with the disease and animal studies to look into effect of type of dietary fat on mammary carcinogenesis. Also, the effect of macro- and micronutrient deficiencies and supplementation were studied in intestinal epithelial cell apoptosis. Further, cisplatin induced apoptotic animal model was developed. Many collaborative research projects are in the field of “Fluorosis”, a major public health problem in India.

His current research focuses on role of enzyme Aldose reductase in various cancers as well as on a diabetes background. Also, research on “Food Allergy (FA) is also a field of interest under which a KAP study was done on Medical Practiones to understand the depth of their understanding regarding FA, including the diagnostic methodologies and treatment aspects. “Food safety studies” with respect to microbiological contamination of food and its prevention is also being looked into. Currently, development and validation of a FA “Questionnaire” to be adopted, to understand the prevalence of FA on a hospital background is to be initiated.

He is a CPCSEA nominee (under Ministry of Animal Husbandry, Govt. of India) and Inspector for various Govt. Organizations and Industry. He is also a trained GLP Assessor working on behalf of National GLP Monitoring Authority of DST, Govt. of India.

He is a Life Member of Indian Association of Pathologists and Microbiologists (IAPM-AP), Nutrition Society of India (NSI), Society of Toxicological Pathologists of India (STPI), Laboratory Animal Scientists Association (LASA) and member, Indian Medical Association (IMA). He is on the teaching faculty of courses in Nutrition as well as Laboratory Animals Sciences.
