Research Interests

My lab studies the ecology, genetics, and evolution of cyanophages living in the coastal waters of Southern New England.  Over the past 16 years, we have collected and characterized 1000s of cyanophages (viruses that infect cyanobacteria) from Narragansett Bay, Rhode Island and adjacent waters.

My research is currently focused on the following questions:

  1. How is genetic diversity generated and maintained within a viral population?
  2. Is the microdiversity observed within viral populations functionally significant?
  3. How diverse are the viral and bacterial genes that influence viral-host interactions?

We are addressing these questions by (a) conducting coevolution experiments in the lab, (b) isolating cyanophages from natural populations over time and characterizing phenotypes related to host interactions (i.e., host range, adsorption rate, and growth curves), and (c) sequencing viral genomes from both coevolution experiments and natural populations.  We are using the results from the coevolution experiments to test predictions about phenotypic and genetic variability in natural viral populations.
