Biogeoscience

Members of the new Biogeoscience group investigate living systems as fundamental components of the Earth System and possibly other planetary systems through the integrated study of biology, geochemistry, and geology. In DEES, students have the opportunity to work with faculty in aquatic, wetland and terrestrial ecology, biological oceanography, evolutionary biology, microbial genomics, biogeochemistry, paleobiology and astrobiology. DEES Biogeosciences faculty conduct research on biodiversity and ecosystem function, ecological responses to climate change, biogeochemical cycling and storage of nutrients and carbon, plant physiology and biooptics (both aquatic and terrestrial), and the application of isotopic, fossil and organic geochemical tracers to the study of climate and Earth history. Fieldwork and lab experiments employ diverse analytical, observational and modeling tools to build understanding of the Biosphere and its interactions within the Earth System, in the past, present and future.

Phycology, cross-kingdom interactions, biogeochemistry, microscopy and, recreationally, the microbiology of fermented foods. 

I am a graduate student in Dr. Sonya Dyhrman's microbial oceanography laboratory; I'm most interested in the molecular underpinnings of how marine microorganisms (and their viruses) interact with each other and their environment, and ultimately biogeochemical implications of these interactions.

I am broadly interested in how marine microbes like phytoplankton interact with their geochemical environment, where I use molecular level tools to study the intersection of microbial physiology and biogeochemistry.

Microbial oceanography group members are using a suite of genome-enabled approaches to examine the distribution and activities of marine phytoplankton, and how they influence cycling of carbon, nitrogen and phosphorus. Our work often uses model cultures to understand and bound field observations made on research cruises that span the from polar to tropical systems. This research emphasis provides advanced training for undergraduates, graduate students, and postdoctoral scholars and it is also used as a framework for the development and implementation of inquiry-based educational activities for children.
