Matthieu is currently a postdoctoral fellow at the UW School of Aquatic and Fishery Sciences working in collaboration with National Marine Fisheries Service (NOAA) at the Alaska Fishery Science Center. His research project focuses on the development of new modeling tools to understand and quantify the potential impacts of climate change on marine living resources. Specifically, he is currently working with Andre Punt, Martin Dorn, Carey McGilliard and Paul Spencer to develop a flexible projection model that allows evaluation of environmental forcing on North Pacific groundfish stocks population dynamics under climate variation.
Matthieu received a Ph.D. in Fisheries Ecology from the Bretagne Occidentale University, France, in 2020. During this project, he used various statistical approaches to investigate the drivers of changes in life history traits of sardine in the Bay of Biscay with the purpose of including them within the stock assessment model of this species.
