Research Interests

Basically, our research evaluates how biotic interactions (with a focus on parasitism), affect the distribution and abundance of aquatic species. We am particularly interested in how parasites affect the demographics of their hosts and how community structure is altered by infectious agents. Although parasites are often common aquatic systems, their roles are poorly understood. Much of our research focuses on biological invasions. Introduced species provide a way to test predictions about the ecology and evolution of host-parasite interactions as well as evaluate the effect of parasites in natural communities. Understanding how parasites affect the demographic success of introduced species and exploring the impact of introduced parasites on native communities will help manage biological invasions and emerging diseases. We work on biological invasions in Panama, the Canal, as well as elsewhere; developing a global perspective on factors driving invasions. We also maintain a strong focus on the ecology and evolution of parasites and diseases in marine and estuarine systems, principally within mangroves.

We don't really focus on specific taxa but we do generally tend to work on fish, crabs, snails and their parasites. We also work on sessile marine invertebrate communities.
