Johnny Ryan's Research Website
Department of Geography, University of Oregon
Welcome to my website. I am Physical Geographer interested in Arctic environmental change and its impact on people at local to global scales. Most of my research involves the use of satellite and uncrewed aerial vehicle (UAV) remote sensing (and fieldwork of course!) to understand key cryospheric processes. My studies of albedo, hydrology and snowfall have directly contributed to forecasts of ice sheet contributions to global sea-level rise (see CV). The significance of this research is reflected by first-author publications in journals such as Science Advances, Nature Communications, and Geophysical Research Letters (see Publications) and media coverage in the New York Times and Earth Magazine.
I am currently an Assistant Professor in the Department of Geography at the University of Oregon where I co-lead the Cryo-hydro Lab for Earth Observation (CLEO). Students in my group are mapping seasonal snow depths using a LiDAR drone, modeling surface energy balance of the Greenland Ice Sheet, remote sensing precipitation from space, and investigating coastal ice accessibility.
