Welcome Day at CREST – A Great Start to the New Academic Year
On October 10, 2024, CREST held its annual Welcome Day, an event dedicated to welcoming new members (research assistants, PhD students, postdoctoral fellows, and faculty members), offering them an introduction to the laboratory through presentations from the management team and thematic leaders.
This year, all CREST sites (CREST-ENSAE Paris, CREST-ENSAI, and CREST-Télécom Paris) gathered at the ENSAE Paris campus.
The presentations provided the new members with a comprehensive understanding of CREST’s institutional environment, particularly its affiliations with the Institut Polytechnique de Paris and the University of Rennes. Each newcomer also had the opportunity to introduce themselves and their research project, fostering exchanges with both new and existing members of CREST.
The thematic leaders highlighted well-being initiatives at CREST, as well as the structure of the doctoral program at IP Paris. The event also allowed the administrative team to outline their roles and share useful recommendations.
Our scientific data engineers demonstrated Onyxia, a solution recently deployed in collaboration with GENES.
Finally, CREST PhD students shared information about various reading groups, other lab initiatives, and teaching opportunities available during the doctoral program.
This event also marked the unveiling of CREST’s new institutional brochure for the academic year, which provides an overview of the lab’s research and teaching activities, as well as its prestigious achievements.

Previous position: Postdoctoral fellow at the Institute for Fiscal Studies.
Marion’s research agenda has two angles. First, she investigates the societal cost of air pollution and the causal impact of climate and environmental policies, with an emphasis on health, productivity and distributional effects. In a second and more early-stage angle, Marion studies the determinants of support for green policies, in particular the role of social norms and identity.
