I studied zoology for my bachelor’s & master’s degrees from the University of Bombay. For my Ph.D. research at Virginia Polytechnic Institute & State University, I used optimization to manage the conflicting habitat needs of two endangered species that interacted as prey (blackbuck) & predator (wolf). In 1991, I obtained a postdoctoral fellowship at the Smithsonian Institution & studied reproductive energetics using doubly labelled water. I joined the Wildlife Institute of India in 1993 & 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 & tiger using VHF, GPS, satellite & recapture telemetry. I continue to be a research associate of the Smithsonian Institution & a member of the IUCN SSC Specialist Group for Wolves & Canids.
