France-BioImaging

A National Research Infrastructure for Biological Imaging

Montpellier

Head of Node: Marcelo Nollmann

The Montpellier node comprises a tight collaboration of research/development teams and microscopy research platforms. The main objective of this FBI node is to develop, implement and provide access of state-of-the-art optical microscopy systems allowing microscopic imaging from unicellular organisms to whole animals. Specifically, our emphasis is on super-resolution and fluctuation microscopies, high-throughput high-content microscopies, and in vivo cellular imaging and manipulation. Our national specificity resides in the use of high-end microscopies to study different aspects of chromatin biology, such as chromosome organization and gene expression.

FBI-Montpellier is composed of a microscopy research and development facility (MARS of the CBS), two microscopy facilities (MRI and IPAM), and two R&D groups (Nollmann and Margeat labs). Several active and synergistic collaborations exist between these different entities in which R&D groups contribute their expertise in optical/instrument development and platforms contribute their savoir-faire in user service and in general logistics.
