Dwayne Estes Ph.D., Director of the Herbarium

Biography

Hi, welcome to my home page! My name is Dwayne Estes. I currently serve as Associate Professor of Biology at Austin Peay State University and have a joint appointment as Biodiversity Explorer with the Botanical Research Institute of Texas (BRIT). I also serve as a Principal Investigator in the Center of Excellence for Field Biology and Director of the APSU Herbarium. I have been studying plants for 22 years and first got bit by the "botany bug" as a sixth grader in 1990. Much of my youth was spent "roaming the hills and hollers" of southeastern Giles County, Tennessee. After graduating from Giles County High School in 1996 I took off a couple of years to find my way. By the time I got back in school in 1999 the chlorophyll was thoroughly "coursin through my veins." I received my B.S. in Plant Biology from Middle Tennessee State University in 2003 and then moved on to pursue a PhD from the University of Tennessee, Knoxville where I graduated in May 2008 from the Dept. of Ecology & Evolutionary Biology. For my PhD I studied the "Systematics of Gratiola (Plantaginaceae)." I started my career at APSU in August 2007. I am enthused about botany more than ever because now I am in the position where I literally have the best of both worlds, the ability to study and conduct research on plants and then the ability to work with and teach students. The research that I do fuels my passion for teaching and vice versa.

Research Interests

Vascular plant systematics (particularly Gratiola, Clematis, Carex, Sisyrinchium, Lysimachia, Penstemon); Tennessee flora; plant communities of Tennessee; prairies, barrens, and rocky outcrops of eastern North America; biogeography of eastern North America.
