Dr. Ramseyer holds a Bachelor of Science in Geographic Science degree from James Madison University, and Master of Science and Doctor of Philosophy degrees in Geography from the University of Georgia. Dr. Ramseyer is a native of southwest Virginia having spent much of his childhood in Abingdon. In 2016, he joined the faculty in the Department of Geography and Geosciences at Salisbury University as an Assistant Professor where he remained until joining the Department of Geography at Virginia Tech in August 2019.
Dr. Ramseyer’s primary area of research focuses on tropical rainfall, particularly in the Caribbean, and how climate change is likely to change drought and flooding. His other published research has examined weather impacts on football player mortality, climate change impacts on severe convective environments, and moisture impacts on Greenland ice melt. His publications have appeared in Climate Dynamics, Journal of Geophysical Research: Atmospheres, International Journal of Climatology, and Science of the Total Environment. He is an active member of the American Geophysical Union, American Meteorological Society, and the American Association of Geographers.
