I am a marine biologist with a special focus on phytoplankton physiology and chemical ecology. I began my research career in 2011 at the Marine Environmental Science Laboratory (LEMAR, France). I also have experience working at the National Oceanic and Atmospheric Administration (NOAA, US) and at the University of Wollongong (UOW, Australia) . I am now working at LEMAR at the University of Western Brittany (UBO, France) and the University of Wollongong (UOW, Australia) studying chemical interactions within phytoplankton.
