With more than 20,000 students, the Université de Lille 1 Sciences et Technologies is the most important University in Northern France in the fields of science and technologies. The University delivers more than 200 different degrees. More than 1000 students are following doctoral studies yearly. The University Lille 1 is currently involved in 22 H2020 projects. Two laboratories (joint units University Lille 1 – CNRS) are involved in the project: the ANATRAC (Trace Analysis) research group at the PhLAM laboratory (Laboratoire de Physique des Lasers, Atomes et Molécules – UMR 8523 CNRS) and the « Combustion » research group at the PC2A laboratory (Laboratoire de Physico-Chimie des Processus de Combustion et de l’Atmosphère – UMR 8522 CNRS). The two groups have developed a long-term collaboration on the application of laser techniques in combustion, in the frame of the Centre d’Etudes et de Recherches Lasers et Applications (CERLA), participating jointly to projects and networks as LABEX CaPPA (Chemical and Physical Properties of the Atmosphere), ANR SOOT, CPER CLIMIBIO, GdR SOOT. Activities are predominantly experimental, but with a very strong coupling with theory.
