CNRS DELEGATION CENTRE-EST
ConférenciersAudrey BEAUSSART,CNRS researcher at the Interdisciplinary Laboratory of Continental Environments of the University of Lorraine and the CNRS, observes bacteria, yeasts and also microalgae mainly thanks to a very powerful microscope called «Atomic Force Microscope». This device allows her to see living cells on an infinitely small scale and to better understand their role in the environment. Hélène JEULIN, lecturer attached to the Laboratory of Physical Chemistry and Microbiology for Materials and the Environment (LCPME) of the University of Lorraine and the CNRS, she is also a hospital practitioner at the CHRU of Nancy, studies viruses in humans and in the environment. Failing to see the viruses themselves, she microscopically observes the host cells of the virus. The image of healthy or infected cells can answer fundamental or applied scientific questions. Martin LAVIALE, lecturer attached to the Interdisciplinary Laboratory of Continental Environments of the University of Lorraine and the CNRS, studies microalgae, especially diatoms, whose diversity is essential to the functioning of aquatic ecosystems. In order to characterize this diversity, he uses artificial intelligence to analyze thousands of images taken under the microscope. He also collaborates with colleagues from the TARA Ocean project on images of marine plankton.

Round Table: See for Understanding the Invisible through Scientific Images. There is a world that is invisible to the naked eye, populated by more amazing living organisms. With various tools, from the classic microscope to those worthy of science fiction films, it is possible to observe this small world and understand how it works. From the environment to human health, come push the doors of the invisible and discover how images are used in scientific research! A short introduction will be made so that you can imagine the scale of our size and time. Each speaker will present their research with a meaningful image. Various aspects can then be discussed during the round table: how are the images produced, how are they used, to whom are they addressed, what could the look of a professional photographer bring?
