Research Interests
Current Research
The goal of my current research is to understand broad-scale patterns in the diversity and dynamics of tropical rainforests. I am particularly interested in how variation in resource availability affects the composition and dynamics of rainforests. To investigate this, I am focusing on the impact of several well-known resource gradients on tropical forest diversity and dynamics: geographic variation in rainfall seasonality, local variation in soil resource availability, and temporal variation in climatic patterns. In each broad project, we are conducting a range of ecophysiological, demographic, community, and biogeographic studies. Understanding how environmental factors constrain species distributions and affect growth and mortality rates is fundamental to predicting the likely impacts of changes in land-use and global climatic conditions on tropical rainforests.
