My research interests address the microbial oxidation of methane, a potent greenhouse gas that emanates through seafloor sediments in staggering amounts. The removal of methane in the marine environment provides a significant sink of this gas, otherwise bound for the atmosphere. Viruses are likely responsible for the majority mortality amongst these methanotrophs. However, we know very little about virus diversity and potential gene transfer via infection of such bacteria and archaea. I employ both geochemical and biological techniques to determine whether virus-host interactions alter the physiology of methane oxidizers, and thus influence the resulting biogeochemical process.
