Welcome to the home page of the Rocap lab, located in the School of Oceanography at the University of Washington. I am a marine microbial ecologist interested in the evolution and ecology of marine bacteria and phytoplankton. We use a variety of approaches in the lab; physiological (growth experiments and pigment analyses), molecular (quantitative PCR, sequencing and expression assays) and computational (phylogenetic analyses, comparative genomics). The multiple projects in the lab all address common questions: How does genetic diversity arise in marine microbial populations, how is it maintained, and how does it influence ecological success.

Our lab is part of the Center for Environmental Genomics, occupying 11,000 square feet of newly renovated lab space in the Benjamin Hall Interdisciplinary Research Building.
