PhD Position in Host-Microbe Symbiosis The Stoy Lab at Florida State University is recruiting graduate students to start in Fall 2026. Our research focuses on investigating the evolutionary drivers of species-rich symbiotic mutualism. We are interested in understanding why some mutualisms involve many partners while others are highly specialized, and the consequences of these divergent evolutionary pathways. We use an evolutionary genetics approach leveraging two complementary systems. One arm of our research program uses the naturally occurring interactions between Coreid insects and their bacterial Caballeronia symbionts. The second arm uses experimental evolution of mutualistically cross-feeding yeast. Students will have opportunities to develop research projects that leverage these tools, population genetics, and molecular genomics to investigate the evolution of mutualism. Interested candidates should email kstoy@fsu.edu with a CV and an explanation of their previous research experience, future research interests, and projects you would like to pursue in the Stoy Lab. I will meet with all candidates by zoom during the Fall 2025 semester. Candidates would apply to the Ecology and Evolution graduate program at FSU, a collegial, exciting, and interdisciplinary environment. FSU is in Florida's panhandle, which is teeming with interesting natural habitats and unique biodiversity. Candidates will be funded through TAships/RAships and encouraged to apply for independent funding. For more information about our lab and research visit the Stoy Lab Website.
