Brief Profile

He Joined ICMR in 1980 and spent initial years in the Food & Drug Toxicology Division of the Institute, wherein he worked on chemical, nutritional and toxicological evaluation of unconventional oils. He has obtained his Master’s Degree in the year 1988 in Applied Zoology from the Central University of Pondicherry. He moved to National Centre for Laboratory Animal Sciences (NCLAS) to pursue Ph.D in Zoology, which was awarded to him in 2002. His doctoral work was on the establishment and characterization of the obese mutant rats established at the centre. He is currently associated with the Animal Facility and is involved in all the centers activities like breeding and supply of animals as well as in training of personnel in handling lab animals both regular and adhoc. He has experience in working with different areas such as In vivo imaging of small animals, mutant breeding. He has been recognized as PhD research supervisor at Osmania University in Zoology. His areas of interest include animal physiology, animal behaviour, and also pre-clinical toxicology. He was instrumental in establishing the “State of the Art” animal physiology laboratory in the centre.

He serves an advisory committee member in health and nutrition for reputed Government bodies like the Department of Science and Technology (DST); Mid-day Meal Programme (MDM) and National Disaster Management Authority (NDMA).
