After a bachelor degree in physics obtained in the university Paris7 Denis Diderot, and a master degree about interdisciplinarity in life sciences obtained in the same university, I start a PhD in the Biophysics team of the Laboratory Jean Perrin under the supervision of Ms. Nelly Henry. My project is to study the adaptative trajectories to perturbations (change of the chemical properties of the medium, change of the flow, etc...) in adhesive multi-species bacterial communities in millifluidic channels.
