Symposium in honor of Claude Boccara

This Friday, January 20, the Langevin Institute is organizing an international scientific symposium in honor of the 80th birthday of our colleague Claude Boccara.

Professor at the Ecole de Physique et de Chimie Industrielles de la Ville de Paris for more than 50 years (!) of which he was Director of Research, he directed the laboratory of Physical Optics of the school, then co-founded the Langevin Institute with Mathias Fink in 2009. His research has been rewarded by numerous prizes, including the Emilia Valori Grand Prize for the application of science awarded in 2022 by the French Academy of Sciences.

Claude Boccara is at the origin of many original measurement methods in the fields of optics and imaging: polarized light, photothermic, detection by mirage effect, near-field optical microscopy, optical coherence tomography. He has also worked on the development of experimental tools to detect gravitational waves using adaptive optical methods (VIRGO interferometer). More recently, he has been a pioneer in optical imaging of biological tissues by acousto-optical imaging, optical coherence tomogaphy and transmission tomography, notably for tumor diagnosis, corneal and retinal imaging. His research work has led him to co-found 3 start-ups.

During this day, we will have the pleasure to listen to many world-classresearchers, at the forefront of research fields that Claude helped to initiate and develop during his prodigious career. You are all welcome to listen to anecdotes about our dear colleague, but especially to (re)discover what recent research in optics owes to this exceptional researcher.

The day can be attended in person in the amphitheater of the Institut de Physique du Globe de Paris, 1 rue Jussieu, or remotely by using a broadcast link via ZOOM, which will be communicated a few days before the 20th.

Registration is free but mandatory through this form ).

Here is the Zoom link to attend the seminar online. You can alternatively connect through the following meeting ID: : 836 8969 6330

We hope to see you there,
The organizing committee of the Langevin Institute
