Research Interests

My work focuses on how disturbance affects biophysical processes of managed ecosystems at scales ranging from the leaf to whole watersheds. Nationally and internationally, my work focuses on how management and climate change affects biophysical processes in a variety of ecosystems that range from Canada's sub-boreal forests and grasslands, northern Michigan's wetlands, mountain ecosystems in Oregon, Washington and Colorado, to managed plantations in Brazil, Argentina, Mexico and Iran. I enjoy interdisciplinary work as my past research has covered the fields of Hydrology, Ecology, Micrometeorology, and Tree Physiology. My skill set is broadly applicable and I am excited to work in new ecosystems to tackle current environmental issues. Ultimately, the goal of my work is to provide insight into how management or climate change will affect the hydrology, stability and productivity of the Earth's ecosystems.
