Description du Projet:

In RCL lab I am analyzing actin homologue MreB from Bacillus subtilis, to study its dynamics and biophysical properties by using TIRF live imaging of in vitro isolated MreB.

Personal description

I am a cell biologist specialized in micromanipulations and in vivo imaging of cells and embryos. I’m interested in cytoskeleton organization, functions and dynamics, on both microtubules and actin. I worked on eukaryotic model systems until now and I am looking forward to discover new things using prokaryotes.
