Research and Teaching

I am an aquatic microbial ecologist and biogeochemist.

Very broadly: I am interested in how microbial diversity affects nutrient cycling in aquatic ecosystems, as well as the basic biology of marine and freshwater archaea.

Specifically: I seek to understand the interplay between microbial populations (archaea in particular) and nitrogen-cycling rates in aquatic ecosystems. I use tools from microbial ecology, ‘omics, cultivation-based microbiology, isotope geochemistry, and bioinformatics. This array of interdisciplinary methods allows my questions to span a wide range of scales, from genes to cells to microbial populations to entire ecosystems. Knowledge of a variety of techniques provides opportunities for undergraduate mentees with diverse scientific interests: ecology, microbiology, oceanography, genomics, computational biology, etc. – anything related to microbes, nitrogen, or water!

While much of my research involves collecting new data from ships or docks and processing them in the lab, my computational projects also take advantage of the rapidly-growing public databases of microbial sequence data.

As an educator, I am interested in developing project-based undergraduate science courses that incorporate field work, lab work, and/or chronological reading of primary literature. I seek to mimic the scientific process in undergraduate courses – e.g., reading journal articles, scientific writing, and collecting, processing, and presenting data. Furthermore, I strive to use inclusive teaching methods that create an open learning community and facilitate success for students from all backgrounds. I have contributed to courses on marine biology, field methods in environmental science, microbiology, and environmental science as a teaching assistant and guest lecturer.

I like to tweet about science and other assorted things.
