Ryan Sullivan

Ryan Sullivan is a professor in the Departments of Chemistry and Mechanical Engineering at Carnegie Mellon University. He is also a faculty member in the Centre for Atmospheric Particle Studies. Sullivan's research interests include atmospheric and analytical chemistry, single-particle analysis, heterogeneous kinetics, and cloud nucleation. His work focuses on developing aircraft-deployable analytical instrumentation to characterize atmospheric particles in real-time, investigating their physicochemical properties, and how these processes affect cloud properties and climate. His research involves instrument development, laboratory experiments, and field measurements.

Ryan C. Sullivan is a Professor in the Department of Chemistry and Department of Mechanical Engineering at Carnegie Mellon University. His research focuses on atmospheric chemistry, analytical chemistry, and environmental chemistry, with an emphasis on aerosol-cloud interactions, water purification, and the chemical complexity of sea spray aerosol. Sullivan's work explores the impact of mineral dust and biological aerosols on precipitation, the role of ice nucleating particles in cloud formation, and the chemical processing of atmospheric particles. His research also investigates the effects of chemical mixing state on hygroscopicity and cloud nucleation properties, as well as the irreversible loss of ice nucleation active sites due to sulfuric acid condensation.
