My research focuses on the diversity and dynamics of Amazonian rain forests in Ecuador. Early work compared the diversity and structure of montane and lowland forests. Currently, I am investigating the diversity and dynamics of hyperdiverse lowland Amazonian forest, and have established a permanent 50 ha Forest Dynamics Plot at Yasuní in collaboration with the Smithsonian Tropical Research Institute (Panama) and the University of Aarhus (Denmark). In addition, I am interested in studying the endangered and endemic plant species of Ecuador. My work has been funded from many sources, including the US National Science Foundation, Andrew Mellon Foundation, European Community, and GEF.
