Our lab works broadly on biogeochemistry and ecosystem science, applied to a wide variety of both theoretical and practical questions. We enjoy trying to understand some of nature's complexity, and we believe strongly in applying objective science to sustaining the biosphere and human society. Our research encompasses a wide range of spatial scales, from microbial to ecosystem, regional, and global. Our research includes a broad range of inter-connected topical areas, illustrated below. Note that much of our research and many of our papers fall into two or more of these categories. Click on a topic to further explore research in the Howarth-Marino lab.
