Marion comes from Saint-Pierre and Miquelon, a French fishermen’s island near Canada. She obtained a MSc in Marine Biology from the University of Brest, France. Marion is mainly interested in theoretical aspects of biology, especially evolutionary biology and the consequences of human harvesting on life-history traits.

In her PhD project within the ConEvolHer, funded by the Norwegian Resaerch Council, Marion is working on energy allocation and fishing-induced changes in growth, condition, reproduction, and behaviour in pelagic fish species, with the Norwegian spring-spawning herring as a model. The aim of her project is to investigate why pelagic species seem not to respond to fishing pressure as life-history theory would predict it.

Marion is employed by the Institute of Marine Research (IMR). Her main supervisor is Katja Enberg. At the University of Bergen she is hosted by the EvoFish group, with Mikko Heino as the co-supervisor.
