I am an environmental epidemiologist working on planetary health and mostly focus on low- and middle-income countries. I currently serve as a Senior Lecturer in Global Population Health at Imperial College London, where I am supporting the leadership and management of the NIHR Global Health Research Centre on Non-Communicable Diseases and Environment Change with India, Bangladesh, and Indonesia as focus countries. My research interests include 1. impacts of global environmental changes such as climate change, biodiversity loss, and land use change on human nutrition, food security, and health, and 2. development and evaluation of transformative solutions to the health impacts of global environmental changes and their drivers. Some of my recent research activities include the Lancet Pathfinder Commission, Lancet Countdown on Health and Climate Change, Complex Urban Systems and Health (CUSSH) consortium, Planetary Health Watch, and DFG Research Unit on Climate Change and Health in Sub Saharan Africa.
