Research in my lab emphasizes biodiversity through field and lab-based approaches that address phylogeny, pollination biology, biogeography, and ecology. My broad interests allow me to combine a variety of scientific approaches, such as DNA sequencing, field observations and surveys, and manipulative experiments, to attempt to explain the evolutionary history and ecology of various plant groups. Since 1994 I have developed and implemented various biodiversity research projects throughout the New World Tropics (especially Ecuador, Peru, Bolivia, Colombia, and Cuba). These projects have helped understand the distribution, taxonomy, and evolutionary relationships of critically endangered flora
