Evan Siemann is an associate professor in the Department of Ecology and Evolutionary Biology at Rice University in Houston, Texas. He received his AB from Cornell University in 1990 and his Ph.D. from the University of Minnesota in 1997. The focus of his research has been investigating how local environmental factors (e.g. enemies, resources, disturbance regime and recruitment limitation) interact with post-invasion adaptation to determine the likelihood and severity of Chinese tallow tree (Sapium sebiferum) invasions into East Texas coastal prairie, mesic forests, and floodplain forests. The results of this research have been highlighted in Science Daily, Environmental News Service, and The Sciences. He has also recently begun to explore the ecosystem level impacts of exotic tree invasions into coastal prairies. His research group is also engaged in a number of applied research projects related to controlling exotic plant and animal invasions into Texas ecosystems.
