Marie Gueguen completed her PhD at the University of Western Ontario in 2019. Her research focuses on the following question: how can the clarification of the structure of scientific theories help us choosing among competing theories, when their observational consequences either are the same or cannot be easily determined. She develops this research program along two main axes: 1) a formal axis, which focuses on showing how artifacts are generated within scientific theories and how their removal can break the alleged equivalence of rival theories; 2) a practice-based approach, in which she studies and formalizes the methods developed by cosmologists to detect artifacts in numerical simulations and assess whether these methods can be suitably applied to scientific theories in general.
Upon leaving the Center, Marie took a post as Research Associate at the Rotman Institute of Philosophy. She will follow that with a Marie Curie fellowship hosted in the Institute of Physics of Rennes 1.
