Dr. Ajith Kumar was Faculty at the Wildlife Institute of India and Salim Ali Centre for Ornithology and Natural History, before joining the WCS-India Program to direct the Masters Program in Wildlife Biology and Conservation at the National Centre for Biological Sciences. He began his wildlife career with a survey of primates in South India in the late 1970s. His doctorate, from Cambridge University, was on the ecology and population dynamics of the lion-tailed macaque. This study introduced him to the tropical rainforest in the Western Ghats, where he and his students later studied small carnivores, rodents and arboreal mammals for the next many years, especially in the context of habitat fragmentation. Sikkim Himalaya has been another area of interest to him, where he and his colleagues have studied mammals, herpetofauna and birds. His research interests include rainforest ecology, primates and small carnivores
