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 in multi-cellular organisms.

Bacterial chromosome structure

Condensin- and replication-mediated dynamic folding of a bacterial chromosome and its origin domain revealed by super-resolution imaging and Hi-C​

TAD organization is not stochastic!

 We used microscopy to measure the absolute contact probabilities between genomic loci. See more here!

Plasmid segregation super-resolved

We used super-resolution and multifocus microscopies to show that plasmids segregate through bacterial nucleoids by the action of ParA  and by relying on the host chromosome scaffold​
