Tropical forest dynamics, plant-soil and plant-fungal interactions, seed ecology
My research concerns the population and community ecology of tropical trees, with a particular interest in understanding how soil nutrient availability and soil microbial communities shape the composition and diversity of tree communities. Much of my work is carried out with collaborators at the Smithsonian Tropical Research Institute, in Panama, either on Barro Colorado Island or at the Fortuna Forest Reserve and Volcan Barú where I maintain a network of forest dynamics plots described here
