University of Central Oklahoma (405) 974-2722 College of Mathematics & Science HOH 208 , Box 177


Gloria Caddell, Ph.D., is currently the associate dean of the College of Mathematics and Science and a professor of biology.  Her interest in nature was sparked as a child by camping and hiking in the forests of southern Alabama, canoeing the streams of the Mobile Delta and walking the Gulf Coast beaches. Caddell's B.A. and M.A. degrees are in anthropology from the University of Alabama, where she specialized in the analysis of archaeological plant remains. She earned a Ph.D. in biology from the University of North Carolina at Chapel Hill.  Her dissertation, on the population genetics and pollination ecology of camellia, is based on research she conducted as a research student in Japan for two and a half years.  Caddell has taught biology at UCO since 1990 and chaired the Department of Biology for four years.  She received the Provost’s Modeling the Way Award (2017), the Neely Excellence in Teaching Award (2010) and the Vanderford Distinguished Teacher Award, College of Mathematics and Science (2006). Her research focuses on the flora of Oklahoma, particularly the native plant communities of gypsum outcrops of northwestern Oklahoma and the pollination of Oklahoma prairie plants.  She is the managing editor of the Oklahoma Native Plant Record and a member of the Flora of Oklahoma Editorial Committee.
