Professional Interests

My research interests center on both theoretical questions regarding forest ecology and biogeography, as well as the application of theory to managing and restoring forests. I focus on both natural and human disturbances to forests, and I use tree rings to help interpret past disturbances and their impacts on forests, such as fire, climate and competition.
