Biography
My research strives to advance our understanding of how Arctic and Boreal (permafrost landscapes) ecosystems have/will respond to climate change and disturbance (permafrost degradation, wildfire, & herbivory). Ecosystem responses to such events are complicated, varying quite dramatically over space and time. Therefore, my research focuses on disentangling this ecological puzzle using a multi-scale observation trifecta (ground-based monitoring, aerial/satellite remote sensing, and empirical/machine-learning/process-based modeling).
