Very happy to share that the @erc.europa.eu has selected PHYTOPOGON for funding! 😁🌱 In this project, we will test whether plants have greenbeard genes — an evolutionary mechanism that could allow them to recognize the genetic identity of their neighbours.

At #Botany2026, I was hoping to start recruiting for my lab group. If you are interested in polyploidy and population genetics, please reach out.
Interested in Polyploidy and Population Genetics?

Florida State University, Join the Gaynor Lab. My lab is open to both Ph.D. and master students through the Ecology and Evolution area in Biological Sciences at FSU - applications are due December 1st!
I also have funding to support a postdoctoral researcher and a technician during my first three years at FSU. The postdoctoral researcher will focus on polyploidy population genomics. The technician will help with lab work including flow cytometry for genome size estimation and DNA sequencing preparation.

If you are interested in joining the lab, please send me an email with a CV/resume and a brief explanation of your research interests and your career goals
