Jayashree Ratnam is community and ecosystems ecologist.
Her past research has focused on drivers of vegetation and nutrient dynamics in African savannas, and cross-continental comparisons of savanna structure and function. She is now working on the under-recognized savanna ecosystems of South Asia with a focus on understanding their history and management, the dynamics of savanna- forest transitions, the roles of fire, drought and herbivores in driving plant traits in these ecosystems, and on their potential responses to ongoing and future climate change. Her work has appeared in well-regarded journals including Philosophical Transactions of the Royal Society, Global Ecology & Biogeography, Nature, Science, Ecology Letters etc.
After she earned her PhD in Biology from Syracuse University USA in 2002, she worked as a Research scientist at the Natural Resources Ecology Laboratory in Colorado, USA and a Research Fellow at the Earth and Biosphere Institute, University of Leeds, UK. She joined the National Center for Biological Sciences, Bangalore, India as a Research Fellow in 2009 and has served as Associate Director of its Wildlife Biology and Conservation Program since 2014.
