Wildlife has been my passion since my early childhood. I studied zoology for my bachelor’s and master’s degrees from the University of Bombay. For my Ph.D. research at Virginia Polytechnic Institute and State University, I used optimization to manage the conflicting habitat needs of two endangered species that interacted as prey (blackbuck) and predator (wolf). In 1991, I obtained a postdoctoral fellowship at the Smithsonian Institution and studied reproductive energetics using doubly labelled water. Later, I taught courses in wildlife conservation and management for the Smithsonian Institution in China, Tanzania, Malaysia, India and the U.S.A. I joined the Wildlife Institute of India in 1993 and have since pursued an active research programme on Indian carnivores. I have supervised research projects on the Indian wolf, striped hyaena, golden jackal, Indian fox, Asiatic lion and tiger using VHF, GPS, satellite and recapture telemetry. I supervise the Conservation Genetics Laboratory at WII. I teach Biometry and Population Ecology for the master’s course in wildlife science and Applied Population Ecology for the diploma programme in wildlife management. I continue to be a research associate of the Smithsonian Institution and a member of the IUCN SSC Specialist Group for Wolves and Canids.
