CARES group develops and leverages air quality models to better understand both ambient and indoor air quality in India. We use a systems scale approach to study:
Nitrogen management: Agriculture and food systems pose a wicked problem - while we need food, fuel, and fiber for our well-being, current production methods have been linked to widespread environmental damage. We use a multi-model system comprising national survey data, agricultural repositories, emissions models, air quality models, and systems-scale LCA approaches to understand tradeoffs between food and the environment. We are also interested in the role of dietary transitions in climate change.
Air quality modelling: We are developing new-generation reduced complexity models and implementing chemical transport models to build predictive capabilities for air pollution, health, and ecosystem assessment.
Indoor air quality: We use hybrid measurement and computational fluid dynamics models to assess ventilation and infectivity metrics in high-occupancy-density microenvironments like classrooms.
