We are a group of marine biologists and paleontologists exploring change and variation in marine ecosystems. Our research focuses on the diverse and complex life found in tropical coastal ecosystems and our research is driven by two main questions:

  1. How do changes in the environment drive evolution and ecological change?
  2. What are the human and natural drivers of ecosystem change on coral reefs and how can defining variation in the past provide direction for future conservation?

Our home is the Smithsonian Tropical Research Institute in Panama. We use a variety of approaches ranging from classical palaeontology and community ecology to molecular biology and isotope chemistry.

We rely heavily on new collections and measurements of modern and fossil biological communities and environments on a regional scale to ask questions of global significance. We study the corals, molluscs, boney fishes, sharks and sponges of tropical seas, and their past as recorded in fossil, archeological and historical records.


Work in the lab is funded by the Panama government (SENACYT), The US National Science Foundation, the National System of Investigators, the Smithsonian Institution and donations from generous philanthropists.
