I use field experiments, long-term demographic studies, mathematical models, and computational approaches to study (1) how the demography and population dynamics of tropical plants are influenced by human activities such as deforestation and climate change, and (2) factors influencing geographic disparities in the production and spread of knowledge, with an emphasis on scholarship from Latin America.

I have previously served as President of the Association for Tropical Biology & Conservation and Editor-in-Chief of the journal Biotropica, and I am currently the Secretary of the Ecological Society of America.
