How air pollution changes the atmosphere’s chemistry, clouds and climate.

Ryan Sullivan is an associate professor of chemistry and mechanical engineering, a faculty member in the Center for Atmospheric Particle Studies and the deputy director of CMU’s Institute for Green Science. He investigates the chemical evolution of environmental pollutants and their impacts on humans, the environment and climate. He focuses on chemical reactions that transform atmospheric particulate matter and the poorly understood role that aerosol particles play in nucleating ice crystals, causing clouds to glaciate and precipitate. Combining approaches from environmental and analytical chemistry with fluid mechanics to design new single-particle analysis instruments allows him to study how individual particles evolve, interact with and impact the environment.

Ryan Sullivan: Understanding Climate Change Through Clouds​

By understanding the properties of individual water particles in the clouds, explains Assistant Professor of Mechanical Engineering and Chemistry, Ryan Sullivan, we can better predict the onset of severe storms, floods, and droughts—and even human-influenced climate change.

The Center for Atmospheric Particle Studies (CAPS)

The CAPS strives to be world leaders in science, engineering and policy covering the full role of fine particulate matter in the atmosphere. Their goal in research is to substantially advance the state of knowledge across this spectrum and both to provide policy-relevant research and to participate directly and actively in the evolution of environmental policy related to particulate matter.
