My research program uses a variety of field and lab techniques to examine competition, predation, and facilitation under ecologically relevant conditions. Working primarily with marine invertebrates on Caribbean coral reefs, I am interested in the biotic and abiotic factors that structure marine communities. As part of my research, I investigate species-specific interactions in the marine environment. Such interactions have long been recognized as important means of speciation in terrestrial systems. Examination of species-specific interactions can provide insight into the evolutionary forces that drive speciation in marine systems.
I am also interested in undergraduate science education, and have worked with the NSF funded FIRST IV professional development project. Current research interests include the use of technology and quantitative reasoning in the classroom as tools for understanding and conveying complex biological processes.
