Dr Ganga Shreedhar is an Assistant Professor of Behavioural Science at the London School of Economics and co-director of the MSc in Behavioural Science programme. Her research explores how different systemic actors-from individuals and communities to organisations-perceive and respond to complex environmental crises, including climate change and biodiversity loss. She investigates what drives sustainable choices around diet, food waste, and collective and conservation actions across these levels, and how behavioural interventions can create transformative change. She teaches Behavioural Science for Planetary Wellbeing and holds a PhD in Environmental Economics from LSE. She is a member of the IUCN behavioural task force.
