Ryan is an associate professor of atmospheric sciences at the University of Ilinois at Urbana-Champaign. Prior to joining UIUC in 2012, he worked as a research associate in Penn State's Department of Geosciences and as a NOAA Climate and Global Change postdoctoral fellow in Penn State's Department of Meteorology. Ryan graduated from Purdue University with a PhD in Earth and Atmospheric Sciences.
Ryan's research seeks to develop a deeper understanding about the physical processes influencing variability within Earth's climate system and to quantify relevant uncertainties using numerical models, observational products, and statistical methods.
His research interests include: Climate Dynamics, Earth System Modeling, Ocean-Atmosphere Interactions, Uncertainty and Risk, Weather and Climate Extremes, Tropical Cyclones, Sea-Level Rise, and Geo-Engineering.
