Research Areas
- Climate Change and Human Health
- Climate change is expected to bring major shifts in weather patterns and can lead to more extreme events like heat waves, drought, and flooding. These climate-related changes affect various health outcomes that can lead to poorer quality of life and push national health systems beyond their limits. To quantify health impacts of climate change, we perform analysis of global level datasets using advanced statistical modeling tools in collaboration with various universities and research institutions internationally. These outputs are useful for the planning of adaptation and mitigation efforts by international institutions and national governments.
