Dr. Havala Olson Taylor Pye

Particles in the atmosphere have implications for public health, visibility, and climate change. Aerosols have a variety of natural and anthropogenic sources and understanding their relative contributions is important for effective air quality management strategies. Havala’s work focuses on developing and applying models such as the Community Multiscale Air Quality Model, CMAQ, to describe and understand particles in the atmosphere.
