Research Interests and Expertise

I am broadly interested in applied and interdisciplinary research on the effects of anthropogenic and natural disturbance on natural resources. A focus of my research activities has been the use of modeling techniques to study the spatial and temporal dynamics of forest ecosystems. In particular, I am applying my expertise to address management and policy issues of forest carbon sequestration that are of concern to national and international climate policy and sustainable forest management.
