Who we are

Who we are

Welcome to Marcelo Nollmann's research group at the Center for Structural Biochemistry of the CNRS/INSERM

We develop single-molecule and advanced microscopy methodologies to understand the mechanisms underlying DNA organization and transcription in multi-cellular organisms.

Click here for links to our multiplexed FISH (Hi-M) acquisition (qudi-CBS) and analysis (pyHiM) software packages.
