Young PhD day

Brigitte Yzel |  19 February 2020

Cerfacs organizes its 5th edition of the Cerfacs Doctoral Students Day on Monday, May 11, 2020. This day will be an opportunity for each doctoral student to present his or her research subject in front of an audience of Cerfacs researchers but also representatives of our industrial and academic partners, as well as selected external guests. Great novelty this year, 10 students have the privilege to participate in a specific training course such as "My thesis in 180 seconds", in order to present their research topic in French and in simple terms. The day will end with the selection of the : best poster, and the best MT180 presentation.Read more


A researcher of CERFACS guest during the France Culture radio show « La méthode scientifique » this week

superadmin |  20 January 2020

Mélanie Rochoux,  a researcher at Cerfacs working on wildfire spread modeling at the interface between CFD simulations and data science, is invited to the France Culture radio show « La méthode scientifique » next Wednesday to talk about megafires. Who are they? How are they formed? What are their impacts? How science can provide insights? The radio show is on Wednesday, January 22nd at 4:00 pm on the France Culture's channel.Read more
