Andrea received her Ph.D. in Organismal Biology and Ecology from the University of Montana (2006), comparing the biochemical effects of the invasive forb, Centaurea stoebe (spotted knapweed), on soil nutrient cycling and plant communities in Centaurea’s native and invaded ranges. Her M.S. (2001) research at San Diego State University looked at the effects of habitat loss and fragmentation on the fitness and genetic diversity of a rare salt marsh daisy. Andrea received a B.S. in Natural Resources from Oregon State University (1998), where she conducted research on the effects of cattle grazing on soil properties in montane riparian meadows. Prior to working at NEON, Andrea was the Director of the Conservation Research Program at the Institute for Applied Ecology, where she managed research, monitoring, and restoration projects focused on the conservation and restoration of native species and habitats. She has also served as an Associate Assistant Professor in the Department of Botany and Plant Pathology at Oregon State University and has worked for the Coast Range Association, the USDA Natural Resources Conservation Service, and as a science educator at the elementary level through upper-division college courses.
