Office Hours: By appointment

Education:

  • B.S., Kennesaw State University, Biology
  • Ph.D., University of Tennessee, Microbiology

Dr. Morris is a microbiologist whose research focuses on the ecology and evolution of marine bacteria. Current work in the Morris Lab, funded by the NSF and the Simons Foundation, is focused on the interactions between algae and heterotrophic bacteria in the ocean, and how these complex interrelationships are evolving under climate change. Dr. Morris is also the director of the ROSE Network, a NSF-funded research coordination network focused on improving undergraduate biology education in both 4-year and community college institutions.

Research Interests

Our research focuses on the base of the marine food web — microbial photosynthetic organisms called phytoplankton. We’re interested in how ecology and evolution intertwine to determine these organisms’ fates, and consequently, the fates of the vast communities they feed.

Our researchers make organisms evolve in the lab. We also get on boats and study our favorite green critters in their native habitats: some of the most exotic environments in the world. We leverage our skills in molecular biology and computation to try to predict what our world will look like 100 years from now.

Ongoing projects in the lab include experimental investigations of the Black Queen Hypothesis, which is a new theory of evolution that predicts that cooperation can evolve in communities that depend on “leaky” biological functions. We’re also interested in using laboratory evolution to find out how quickly important marine algal species can adapt to the changes humans are causing to their environments. There are also diverse other projects ongoing, led largely by the ingenuity and interests of our graduate students, ranging from education research to nanotech medical applications. We’re very open-minded — if you’ve got research interests in microbial evolution and are looking for a lab to work in, send us an email at This email address is being protected from spambots.
