Jeremy Johnson

Ph.D.
Academic Statement

I became interested in forest ecology while growing up near the front range of the Rocky Mountains in Colorado. After completing my BS in natural resources at Colorado State University I spent several years working for the National Park Service and the US Forest Service (both in Arizona) before completing a PhD in geography focusing on forest landscape genetics at Texas A&M University. I have held positions as a visiting assistant professor at Texas A&M University teaching biogeography and I’ve held a joint postdoctoral appointment with Northern Arizona University in the School of Forestry and with the USDA Forest Service at the Dorena Genetic Resource Center in Cottage Grove, Oregon where I was able to spend my time surrounded by the tall trees of the Pacific Northwest.

I am a forest ecologist and geneticist with broad teaching and research interests geared towards understanding the spatial and temporal patterns of how forests respond to multiple threats associated with global ecological change by specializing in the use of geographic, landscape ecological, and genetic tools and theory. Specifically, I investigate patterns of plant movement through seed dispersal, patterns of local adaption and natural genetic resistance to invasive forest diseases. My goal is to ensure the long-term survival of forests with effective conservation interventions and management by training the next generation of ecologists and naturalists.
