I am a researcher at the Smithsonian Tropical Research Institute in Panama. Using both broad-scale environmental sampling and experimental manipulations of small scale model systems, I focus in particular on the following three questions:

​

• What are the nature and causes of biodiversity patterns in the ocean?

​

• How do these biodiversity patterns influence ecosystem function?

​

• How do ecological interactions (i.e., trophic and symbiotic) promote the stability and resilience of marine communities?
