I center my research on understanding the interplay between the biosphere and the physical world. In recent years, I have focused my primary effort on exploring and understanding subseafloor life – an enigmatic global biome that remains largely untouched by human activity. I routinely lead ocean drilling and coring expeditions to advance understanding of this biome. Studies to date have significantly advanced understanding of the size, community compositions, and gross energy fluxes of the marine sedimentary biome. However, many fundamental aspects of this biome are not yet understood, including how subseafloor organisms are adapted for their environments, how they interact with each other, how they evolve, and how their extant communities were shaped by past oceanic conditions. My current research projects are focused on advancing understanding of these fundamental topics.
