Jason Knouft, Ph.D.


Courses Taught

Biogeography, GIS in Biology, Advanced Ecology


Ph.D., University of Illinois 

Research Interests

Current research interests are primarily focused on the effects of human activities (e.g., climate and land use change) on watershed hydrology, water quality, and the distribution of aquatic taxa across multiple spatial scales. A goal of this work is to develop hydrologically-based GIS applications for the study of aquatic biodiversity.
