Our Research Nuclei


We have a passion for extreme weather. Tornadoes, hurricanes, and floods are examples of hazards studied by our group.


Our group is interested in the variability of extreme weather on climate timescales. This includes any potential for change in projected future climates.


Perhaps the most important research focus of our group is on how weather and climate extremes impact humans and our economy.
