I am a physical geographer with expertise in meteorology and climatology. My research topics are broad, but they consistently involve weather data being applied to real-world problems across multiple disciplines. Some of my most recent research has been focused on tornado climatology, weather-suicide relationships, and weather effects on wildlife.
