Assistant Professor



Dr. Johnson is a hydrometeorologist and climate scientist from the San Francisco Bay Area. He completed his B.S. in meteorology at the University of Oklahoma, M.S. in atmospheric science at Ball State University, and PhD in climate science at Utah State University. He also was a postdoc scholar at Purdue University. 

Dr. Johnson has experience in operational forecasting and research. He previously held a position at an energy company as a meteorologist, has served on the American Meteorological Society Energy Committee, and has provided radio forecasts to Utah's NPR affiliate. His research interests are interdisciplinary within the earth system, such as the remote ocean impact on midlatitude climates, seasonal tropical cyclone landfall risk, drought predictability, and inter-basin interactions.
