My research is focused on four aspects of tropical rain forests:

(1) Amazonian forest regeneration as a function of land use history;
(2) Ephemeral and lasting effects of El Niños, fires, floods & fragmentation;
(3) Adaptive strategies of trees in wood deposition and biomass allocation;
(4) Comparative tropical dynamics -- how many rainforests are there?
