Marie obtained a Master degree in Neurosciences at the University of Lyon 1 in 2019, during which time she first joined the team for an internship. Thereafter, she started her PhD project under the supervision of Sylvia Wirth. Marie explores the neural correlates underlying spatial navigation by recording single-unit brain activities of monkeys while they perform orientation tasks in virtual reality. Her work centers on the hippocampus, as well as other structures to which it is connected, such as the posterior parietal, retrosplenial, and posterior cingulate cortices. Marie's research is supported by the Agence Nationale de la Recherche.
