Anurag Tripathi

Research Scientist

Food Toxicology Division
Indian Institute of Toxicology Research


Dr Anurag Tripathi got his MS degree (2004) and later Ph.D (2008) in Biotechnology from School of Biotechnology, Banaras Hindu University, India. He started his career as an immunologist and his Ph.D work was dedicated to exploration of fundamental regulatory links between innate immunity and endocrine system, where he could show that pituitary hormones Prolactin and Somatotropin could direct the response of macrophages towards classical activation. Following his Ph.D, he moved to CSIR-Indian Institute of Toxicology Research as Scientist and made significant contributions to the area of Food, Drug and Chemical Toxicology and Nanomaterial toxicology. He has worked on a variety of projects having industrial and societal relevance including Grant-in-Aid projects and CSIR network projects focused on new paradigms in investigative toxicology, applications and impact of nanomaterials, food additives, contaminants and adulterants on public safety, human health and environment. Dr Tripathi has authored more than 30 publications in international peer reviewed journals of Immunology and Toxicology.
