In the newly released 2022 Top Scientist rankings by Research.com, 12 GEOG researchers ranked among the Top 1000 Environmental Sciences researchers in the United States, and seven ranked among the Top 1000 worldwide.

According to Research.com, the goal of their rankings is to “inspire scholars, entrepreneurs, and decision-makers worldwide to explore where leading experts are heading and to provide an opportunity for the entire scientific community to discover who the leading experts in specific fields of research, in different countries, or even within research institutions are."
