Online Seminar on Navigating in the dark: validating models in context of high uncertainties

Abstract

The goal of this talk is to analyse how models can be validated in those contexts where both the observations and the theoretical predictions are highly uncertain. In particular, she analyses the role that numerical methods can play in better understanding what a model is sensitive to, in exploiting discrepancies between observations and models and in further constraining them until a situation where a meaningful assessment of an (dis)agreement between predictions and observations can be reached.

Biography

Marie Gueguen is a Marie Curie fellow at the Institute of Physics of Rennes 1. She completed her PhD in Philosophy of Science in 2019 at the University of Western Ontario. Her research focuses on the role of numerical methods in helping to build, develop and assess the reliability of scientific methods. Her present project aims to analyze  the main difficulties that can hinder interdisciplinary work in astrochemistry, taking as a starting point the identification, quantification and communication of uncertainties across different domains - from theoretical calculations to chemical models and to laboratory astrophysics.
