Research Emphases

Synoptic meteorology, high-impact weather, climate change

Specific Research Endeavors

My primary research interests involve high-impact weather in the context of climate change and short-term predictability. I utilize high-resolution models to simulate phenomena such as tropical cyclones, extratropical transition events, snow storms, and atmospheric rivers to examine how these systems and their impacts may change 50–100 years from now. I am also interested in short-term predictability challenges such as the formation of mesoscale frontal waves along atmospheric rivers.
