Jay Alder


Jay Alder is a Physical Scientist based in Corvallis, Oregon with the Geoscience and Environmental Change Science Center. He received a BS in Computer and Environmental Sciences from the University of California, Riverside and his MS and PhD in Geography from Oregon State University. Jay maintains a courtesy faculty position in the College of Earth, Ocean, and Atmospheric Sciences at Oregon State University. Jay is a climate modeler with interests in past, present and future climate change, dynamically downscaling, hydroclimate, and model visualization. He is interested in helping to make climate model information accessible and useful to other scientific disciplines seeking to incorporate future climate change projections into their own work.
