I am an environmental microbial ecologist who strives to understand the physiology and ecology of marine and aquatic microbes around the world. I use 'omics methods and targeted gene approaches, as well as culturing and physiological experimentation, to gain a multifaceted view of microbes in their environment. I study all of the smallest organisms, including viruses, bacteria, archaea, and microbial eukaryotes, to understand their ecology and function, how microbial communities contribute to global biogeochemical cycles, and how these communities are responding to a changing world.
