We are a group of molecular ecologists and evolutionary biologists exploring biological diversity in tropical environments.  We use DNA and RNA as tools to inform the fields of ecology, invasion and conservation biology, systematics, and evolutionary biology, providing genetic, geographic, and historical answers to biological questions.  We work in both terrestrial and aquatic environments and our projects explore wide-ranging subjects such as microbial community diversity, the geographic origins of invasive species, and genetic diversity in both common and endangered species.  The EEG lab is a resource to the STRI community providing space and common-use equipment for short and long-term projects in ecology and evolutionary biology.  We also provide one-on-one training and annual workshops to teach students and collaborators how to select and use genetic markers and analytical tools.  Students and postdocs participate in staff-sponsored projects or conduct their own research.
