John Campbell


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. Ride hard, die free.
