“I used to be a social worker in Connecticut and later in Miami, helping people with disabilities live independently in the community.  I really enjoyed that work and always came home at night feeling like I was making a difference in the world.  My work now looks very different from my social worker days, but I do still get that sense of making some small difference and that’s important to me.”

Dr. Jason Dunion specializes in satellite remote sensing of hurricanes and has led the development of several new satellite products for monitoring tropical cyclones, Saharan dust storms, and the diurnal cycle of hurricanes. His research has also included reconstructing wind fields of several historical landfalling hurricanes, including 1960 Donna and 1965 Besty, developing new climatological atmospheric soundings for the North Atlantic, and leading the development of a new forecast model (the TC Genesis Index) for predicting tropical cyclone genesis. Dunion has acted as chief scientist on several Hurricane Hunter research missions using NOAA’s high altitude jet and P-3 Orions and has flown on over 50 hurricane hunter flights. He also has served as Director of the Hurricane Research Division’s Field Program.
