The Team

Possibly you?

I have an open postdoctoral position to study cyanophage-Synechococcus interactions and dynamics.

I am also seeking a PhD student for Spring 2023. Both will contribute to an NSF-funded project studying the phylogenetic and genomic determinants of host range in Synechococcus and cyanophage in Narragansett Bay, Rhode Island in collaboration with Dr. Marcie Marston.
Please contact me for more information. Information on our PhD program and how to apply can be found here.

Undergraduate students
If you are interesting in joining the lab or learning more about our research, please contact me via email as well.

Master’s students
If they qualify, undergraduate students working in my lab, may be able to continue their research an earn a master’s degree through the Biology Department’s accelerated degree program (ADP). Note that we do not currently accept master’s students from other institutions.

Principle Investigator

Dr. Nathan Ahlgren

Dr. Ahlgren leads the lab in studying the interactions of microbes with environment, with each other, and with larger organism. See the Projects page for more info on the lab’s current research. Full details of Dr. Ahlgren’s background and training are available in his C.V.

Postdoctoral fellows

See above for available position working on phage-host interactions.

PhD students

Emily Dart is interested in understanding how interactions between marine cyanobacteria and phage that infect them (cyanophage) shape the diversity and community composition of both. Her work in particular focuses on time-series studies, including those at the San Pedro Oceaon Time-Series (SPOT), to study how phage-host interactions manifest in the context of seasonal forcing of host communities. She is a recipient of NSF’s Graduate Research Fellowships Program (GRFP)

Shafer Belisle is investigating how adaptation to varying concentrations of iron in the oceans shapes the community structure, genomic variation, and physiological responses of various marine Synechococcus ecotypes.
