Mathias Cohen graduated in 2012 as Expert in Biotechnology Engineering from Sup’Biotech, Villejuif (France). Then he obtained a Master in Biology, with a specialization in molecular and cellular biology, at the University of Sherbrooke (Canada) in 2017. During this research master, he worked in the group of Peter Moffett, that focuses on the study of the plant innate immune system. He studied the translational control of Arabidopsis thaliana genes in the specific context of the Effector-Triggered Immunity, as well as the molecular mechanisms governing processing bodies formation during plant-virus interactions. In 2018, he started to work as an engineer in the lab of Isabelle Jupin, in the Institut Jacques Monod, Paris (France). His work concerned the study of plant-pathogen interactions between Arabidopsis thaliana and the Turnip Yellow Mosaic Virus. In October 2020, he started a joint PhD between the CCARS group of Pr. Graham Noctor (Climate Change and Redox Signaling, IPS2, Universite Paris-Saclay, France) and the OSS group of Pr. Frank Van Breusegem (Oxidative Stress Signaling, PSB, VIB-UGent, Belgium). The topic of his PhD is the elucidation of the mechanisms in play in the activation of the salicylic acid pathway by environmental and redox factors in Arabidopsis thaliana.
