Dr. PV. Mohanan is a Fellow of the National Academy of Science and Royal Society of Biologists, UK. He was a JSPS Post-Doctoral Fellow at the University of Tsukuba, Japan, in the field of Neurotoxicity. He joined Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST), Govt. of India, in 1989. As a toxicologist, he has been intimately associated with all the medical devices/technologies developed at SCTIMST. Currently, he heads the Division of Toxicology and a visiting professor and visiting researcher at Toyo University, Japan, and a Certified Biological Safety Specialist. He received a lifetime achievement award from the Society of Toxicology India for the outstanding contribution to toxicology research. Dr. Mohanan made significant contributions to the development of medical device regulations in India. He received a certificate of appreciation from the Hon. Minister of Science and Technology, Govt. of India, contributed to getting full adherent status on GLP from the OECD. He has authored more than 250   publications and edited 4 books. Presently, he is the Secretary-General of Society of Toxicology, India, and General Secretary of Indian JSPS Alumni Association.
