Hi there! My research in ecosystem ecology addresses linkages between plant diversity and ecosystem function, and ecosystem responses to disturbance. I focus on community change, riparian forest ecology, soil carbon, nutrient cycling, root dynamics, tree physiology, and forest carbon cycling. Please feel free to contact me with interest in my research. Also check out the Lab page with links to more research from my lab.
Here are a few highlights:
- I have been especially interested in linkages between tree molecular genetics and ecosystem ecology of riparian forests in the West, and Southwest (USA; see links to the cottonwood system at our lab page).
- My work with tree roots has taken me belowground using underground camera technology.
- Our lab’s work on temperate rainforest carbon balance continues, and we are continually updating our long-term data set on local forest and soil carbon stores and fluxes (see EEON).
- My lab runs a project measuring long-term plots examining forest understory plant recovery following the eruption of Mount St. Helens in 1980
My teaching (Evergreen Faculty member since 2005) allows me to work in an even broader array of ecosystems because my classes often focus on conducting field studies and hands-on ecological science. Recent remote field sites I have worked in include the Skokomish River (WA), Mount Saint Helens (WA), Cibola National Wildlife Refuge (AZ), Grand Canyon (AZ), The Sinlahekin Valley (WA), the Metolius River (OR), and the prairies of the southern Puget Sound lowlands (WA). Some recent classes I’ve taught include Temperate Rainforests: Biogeochemistry, Field Ecology, Trees, Plant ecology and Physiology, Water in the West: History and Ecology, Field and Laboratory Biology in Southwestern Ecosystems, The Olympic Peninsula, Genes to Ecosystems, Introduction to Environmental Studies, Temperate Rainforests, Plant Ecology and Physiology, and Field Ecology.
