Area(s) of Expertise

My work uses computer models to explore interdisciplinary questions related to air pollution, climate change, and environmental policy. The research focuses on developing tools based on numerical methods, uncertainty analysis, and integrated assessment modeling to simulate interactions between environmental and human systems. At NC State University, I lead a modeling group that aims to bridge the vast range of spatial and temporal scales at which these interactions occur. Current research includes efforts to simulate the effects of wildland fires on air pollution, evaluate uncertainty in projections of climate change impacts on air quality and health, and develop new computational methods for environmental and earth systems modeling.
