Research Interests

Storms, extreme weather, mesoscale processes, surface-atmosphere interactions and how climate change may affect extreme weather in the future. Research mainly relates to warm season processes, including convection initiation, thunderstorms and associated severe weather, as well as surface contributions via evapotranspiration and mesoscale boundaries.

Current projects include: Northern Tornadoes Project (NTP), Northern Hail Project (NHP), and Global Water Futures (GWF) – Pillar 3: Climate-Related Precipitation Extremes
