Jonathan Myers – Associate Professor

Jonathan explores the processes that determine the assembly, diversity, and dynamics of ecological communities across local, landscape, and biogeographic scales. He earned an associate degree in Forest Recreation from Paul Smith’s College in 1999, a BS in Biological Sciences (Ecology & Evolutionary Biology) from Cornell University in 2002, a MS in Interdisciplinary Ecology in the Department of Botany at the University of Florida in 2005, and a PhD in Biological Sciences (Systematics, Ecology and Evolution) from Louisiana State University in 2010. Prior to joining the faculty in the Department of Biology at Washington University, Jonathan held a postdoctoral fellowship at Washington University’s Tyson Research Center (2010-2012). Jonathan enjoys traveling, music from around the world, photography, biking, birding, camping and hiking, fly fishing, soccer, and chess.

Elliott Smith – Research Technician

Elliott joined our research team in Summer 2023 and co-leads our field research and the third census of the ForestGEO Plot at Tyson Research Center. He earned a BS in Ecology, Evolution, and Biodiversity from the University of Michigan in 2022. While at Michigan, his research focused on grassland community assembly, plant-arthropod interactions, and the effect of climate change on insect pollinators. When he is not censusing forest plots, Elliott will frequently be out and about exploring St. Louis, developing his amateur DJ skills, or finding species to add to his iNaturalist profile.
