I am a tropical botanist in the broadest sense, with active research projects in ecology, systematics and conservation. Linking these apparently disparate areas is a long-term focus on the seed and seedling stages of the life cycle. My first projects 25 years ago in Panama were community level studies of the earliest stages of forest regeneration after earthquake-caused landslides and the phenology of seed dispersal and germination. I've recently returned to the latter topic by initiating a comparative phenological study in the Ecuador. Crucial to the success of my early projects was learning to identify seedlings, which are very different from adults. Building on this early expertise, I've championed the need to produce seedling identification guides for ecological and conservation work and to incorporate seedling characters into systematic studies and endeavored to fill this need. An interest in soil seed banks has also lead me into systematic work on pioneer species, which make up the bulk of species found in tropical soil. It is difficult to work in tropical forests without contributing toward their conservation, so I've lead conservation projects in both Ecuador and Belize. Most of my recent projects are in collaboration with colleagues in Latin America, Europe, and the United States, are funded by grants that I have written, and have provided research opportunities for students in the UK and Ecuador.
