About
Dr. Matthew J. Church is a leading microbial oceanographer whose research focuses on the biogeochemical cycling of nitrogen in the world’s oceans, particularly the role of nitrogen-fixing microorganisms (diazotrophs). His work has fundamentally advanced our understanding of how these keystone species control marine productivity and carbon export in oligotrophic ecosystems. In a landmark 2014 study (79 citations), Church and his team deployed an "ecogenomic sensor" in the North Pacific Ocean, revealing real-time environmental controls on N2-fixing microorganisms and demonstrating how these organisms drive much of the ocean’s new nitrogen production. With over 10,000 total citations, his research integrates molecular tools, field observations, and autonomous sensor technology to unravel the complex interactions between microbial communities and ocean chemistry. Church’s contributions have been recognized through prestigious awards and leadership roles in major oceanographic programs, making him a pivotal figure in understanding how marine microbes regulate global nutrient cycles and respond to climate change.
