PROFESSIONAL EXPERIENCE

2006-present Assistant Professor, Department of Plant & Soil Sciences, University of Kentucky
2002-2006 Postdoctoral Fellow, Department of Biology, Duke University


EDUCATION

2002 - Ph.D. in Ecology, Colorado State University
1998 - M.S. in Rangeland Ecology & Management, Texas A&M University

RESEARCH INTERESTS

My research program seeks to identify the main ecological factors controlling grassland structure and function. Specifically, my lab explores the effects of fungal endophyte symbioses on grassland ecosystem processes, and evaluates how grasslands will respond to global change factors, such as alterations to climate, land use, ultraviolet radiation, and invasive species abundance.
