In a few words

Charlotte Guyomar completed her Master's degree “Fundamental and Applied Microbiology” at the University of Rennes 1. She then continued as a PhD student at the IGDR in the “Ribosome Bacteria and Stress” team, under the supervision of Pr. Reynald Gillet (2015-2018). Then, Charlotte went on a 6-month post-doctoral fellowship at the University of Oxford (Sir William Dunn School of Pathology), under the supervision of Dr. Tanmay Bharat (2019). She is now a CNRS post-doctoral fellow in the "Microtubules, from Tubulin to Spindles" team.
