I am a marine molecular biologist with a particular interest in algal chronobiology.
I earned my PhD in 2009 from the University of Paris VI, where I investigated the mechanisms underlying copper tolerance in marine brown algae. From 2009 to 2011, I pursued postdoctoral research at the University of Lorient (France) focusing on adhesion proteins in marine biofilm bacteria. In 2011, I completed a short research stay at the Catholic University of Chile to examine grazing-induced defensive mechanisms in brown algae.
Between 2012 and 2016, I worked as a postdoctoral researcher at VIB/Ghent University, characterizing novel protein components involved in the crosstalk between light and jasmonate signaling in plants. I then joined Sorbonne University as a senior postdoc, investigating the molecular basis of circadian rhythms in marine diatoms. From 2019 to 2023, I returned to VIB/Ghent University as a senior postdoctoral researcher studying how the phytohormone jasmonic acid regulates triterpene metabolism in plants.
From 2023 I was appointed as a junior Professor at the CNRS – Station Biologique de Roscoff. My current research focuses on the chronobiology of brown algae, with a particular emphasis on their circalunar clock.
