Stotra’s research program follows the triumphs and tragedies of individual lions in multiple populations to understand i) eco-evo of lion societies, ii) fission-fusion dynamics, and iii) mating strategies. Current and past research projects include a long-term behavioral and population ecology study on Asiatic lions in India, population estimation and behavior of a coastal/mangrove population of lions in Saadani, Tanzania, and a collaborative project on lions in Tsavo, Kenya. These projects adopt observational, remote and genetic approaches to study the proximate and ultimate mechanisms of lion behavior.
