Educational Background
| Courses Taught | Previous Graduate Students | Publications


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.

Educational Background

Ph.D. Geography, Arizona State University (2005)
M.S. Geography, University of Georgia (2002)
B.S. Geosciences (Meteorology), Mississippi State University (2000)


Courses Taught

Elements of Physical Geography
Introduction to World Geography
Climatology
Weather Analysis
