Dwayne Estes

Dwayne Estes serves as Full Professor of Biology, Principal Investigator for the Center of Excellence for Field Biology, and Executive Director of the Southeastern Grasslands Institute (SGI). Dwayne’s research interests include the flora, ecology, history, and biogeography of the Southeastern U.S. with emphasis on grasslands and discovery of new plant species. He has published 20+ publications and co-authored the Guide to the Vascular Plants of Tennessee published in 2015 by the University of Tennessee Press.

He enjoys mentoring his graduate students.  In the past several years he and his collaborators have been awarded two grants from the National Science Foundation to help build and enhance natural history collections at APSU. In January 2018 he co-founded SGI. Under his leadership, SGI has secured more than $5 million in funding and has grown to a team of more than 20 people. He has been active in building diverse support for Southeastern US grasslands conservation, including bringing together philanthropists, government agencies, non-profits, corporate and small-business partners, private landowners and ranchers, historians, educators, and citizen scientists.
