Disturbance ecology, forest succession, functional ecology

Educational Background: 
  • PhD, Oregon State University, 2004
  • MS, University of Wisconsin-Madison, 1997
  • BA, Reed College, 1991
Research Interests: 

My research interests center on forest disturbance and its effect on primary production, trophic-transfer, decomposition, and combustion with a special focus on how these processes operate in early-seral communities. Most of my research is conducted in the Pacific coast of North America where harvest, and wildfire, are the predominant agents of disturbance, however, my collaborators and I are also investigating ecosystem function in forests impacted by wind-storms, insect mortality, volcanic eruption, and climate change in various locations throughout North America and the globe. My work is primarily hypothesis-driven involving a combination of field observations and simulation modeling. Whether it be framing questions, interpreting data, or crafting narratives, I am guided equally by a desire to advance theory and inform decision makers.

Current/Recent Programs: 
  • Understanding the unique functionality of early-seral pre-forest ecosystems
  • Compounded effects of disturbance and climate change in the Idaho Rockies
  • Effects of disturbance on net ecosystem carbon balance in the Pacific Northwest
  • Wildfire and Carbon emissions
  • Consequences of fuel-reduction and wildfire on forest biomass
  • Ecological impacts of the 2002 Biscuit Fire
  • Untangling the unique consequences of compound disturbances
