Stephen C Phillips, PhD

Steve Phillips is fascinated by gas hydrate systems and early diagenesis in marine sediments. He aims to better understand these systems by integrating sedimentology, geochemistry, and physical property measurements as part of multidisciplinary scientific drilling expeditions. He has worked in the Gulf of Mexico, Bay of Bengal, Cascadia Margin, and offshore Japan.
