Lancement de la Chaire Impact Investing
Welcome at CREST: Introducing our latest recruits.
Each year, CREST goes beyond its borders to find new minds to keep on offering pioneer research. This year, CREST was able to attract new talents from all around the world (Canada, France, Italy, Switzerland, UEA, UK and USA). These new recruits bring with them a wealth of knowledge, diverse experiences, and a passion for pushing the boundaries of their respective fields. New recruits is always very much appreciated by our PhD students and students from ENSAE Paris, ENSAI and École polytechnique, where they may teach as they arrive with a different background and knowledge base.
As CREST continues to produce groundbreaking research about and for society, the arrival of these scholars marks a significant milestone in our journey. Each professor brings unique expertise that will not only enhance our ongoing projects but also open new avenues for exploration and discovery.
In this article, we will introduce you to our new researchers, delve into their backgrounds, and share their specializations that will contribute to the vibrant research environment at CREST.

Yameng Fan, Assistant Professor (ENSAI)
Interests: Macroeconomics of labor markets, political economy, market power and spatial economics.
Previous position: PhD in Economics from Universitat Pompeu Fabra.
Florian Grosset, Assistant Professor (ENSAE Paris, Institut Polytechnique de Paris)
Interests: Development and environmental economics with interests in labor and firms
Previous position: PhD in Sustainable Development from Columbia University
The first strand of his research focuses on labor and networks in lower-income countries. His work explores how individuals’ labor supply decisions are influenced by their social network members, primarily with field experiments. The second strand of Florian’s research focuses on firms’ responses to environmental changes. It combines insights from the natural sciences with applied micro-economic tools for causal identification.
Marion Leroutier, Assistant Professor (ENSAE Paris, Institut Polytechnique de Paris)
Interests: Applied Environmental Economics focusing on two major environmental issues, ambient air pollution and climate change.
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.
Bertille Picard, Assistant Professor (ENSAI)
Interests: Econometrics, Machine Learning applied to policy evaluation and inequalities.
Previous position: PhD in Economics at Aix-Marseille School of Economics (AMSE)
Yuki Tamura, Assistant Professor (École polytechnique, Institut Polytechnique de Paris)
Interests: Micoeconomic Theory, Market Design, Social Choice and Political Economy.
Previous position: Postdoctoral Associate at the Center for Behavioral Institutional Design, NUY Abu Dhabi.
Finance-Insurance
Roxana Dumitrescu, Associate Professor (ENSAE Paris, Institut Polytechnique de Paris)
Interests: Financial Mathematics, Stochastic Control, Stochastic Differential Games, Mean-field Games, Backward Stochastic Differential Equations, Energy Markets, Machine Learning.
Previous position: Associate Professor in Financial Mathematics at King’s College of London.
Sociology
Samuel Rufat, Assistant Professor (École polytechnique, Institut Polytechnique de Paris)
Interests: Urban Geography, Urban Studies, Spatial Analysis, Socio-Economic Inequalities, Segregation, Socio-Spatial Reconfigurations, Environmental justice, …

Interests: Inequality, Poverty, and mobility, Community and Urban Sociology, Race, Gender and Class, Cultural Sociology, Social Psychology, Computational Social Science, Mixed Methods.
Previous position: PhD in Sociology at Stanford University.
Hesu’s research asks longstanding questions about spatial inequality in urban sociology: Why do some neighborhoods (or cities) grow by attracting people and capital while others do not? How does this place stratification intersect with racial and class-based inequalities? Combining experimental, computational, and qualitative approaches, she interrogates high-status consumers and place entrepreneurs – such as business owners, landlords, and travel writers – who have the power to mold physical, economic, and symbolic urban landscapes.
Statistics
Vincent Divol, Assistant Professor (ENSAE Paris, Institut Polytechnique de Paris)
Interests: Topics at the intersection of statistics and geometry, including statistical optimal transport, geometric inference and topological data analysis.

Beyond the PhD – CREST Series 2: How would you define a PhD?
Last year, CREST introduced a new series of videos on the PhD theme. Léa Bou Sleiman & Martin Mugnier were interviewed for this first episode of “Beyond the PhD”. The 4th year economics PhD students present their career at CREST and their participation in the International Job Market.
In 2024, the Beyond the PhD series is focused on the definition of a PhD.
In doing so, four PhD students from CREST have participated in this interview series:
- Reda Alami Chentoufi, 1st year PhD student in Finance-Insurance (CREST-GENES)
- Emma Bonutti d’Agostini, 1st year PhD student in Sociology (CREST-GENES)
- Yiyun Zheng, 2nd year PhD student in Economics (CREST-Ecole polytechnique)
- Clara Carlier, 3rd year PhD student in Statistics (CREST-GENES)
With the participation of Prof. Emmanuelle Taugourdeau, Research Director at CNRS and Deputy Director at CREST, all four PhD students answered some questions about the PhD program: how would they describe it, what is of importance in a PhD and their recommendations to future PhD students.
All videos are now available on the CREST’s YouTube account.
We want here to promote the interview highlights that key points of all interviews in one.
Below, you will find all videos available in the scope of the Beyond the PhD video series 2.

Alicia Bassière wins second place at the Rencontres Technology for Change 2024.
Alicia Bassière is a 4th year PhD student at CREST-Ecole polytechnique in energy economics, specializing mainly in the electricity market, supervised by David Benatia and Peter Tankov.
Alicia is committed to the fight against global warming, focusing on energy as a fundamental component.
For the third edition of the Rencontres Technology for Change, Alicia won second place during the Pitch for Change competition based on the 180-second thesis principle.
Alicia was able to present her thesis work, which involves modeling uncertainty in long-term investments in power generation capacity. In particular, she is working on various sources of uncertainty: electricity consumption, fuel prices, the number of players in the market and renewable production. Alicia uses advanced probabilistic methods for this, which she has popularized as tarot cards.
Beyond her thesis, Alicia is passionate about making economic research and the energy transition accessible to the general public. To this end, she actively participates in events promoting science and collaborates with journalists. In 2022, she joined the TF1 Group’s Committee of Environmental Experts to improve journalists’ understanding of energy and climate issues, occasionally appearing on the French TV channel LCI to share ideas.
As part of her scientific activity, Alicia Bassière is working on several research projects, jointly with her thesis supervisors:
– Moving forward blindly: capacity planning, uncertainty and environmental targets (joint work with David Benatia)
– A mean-field game model of electricity market dynamics (joint work with Peter Tankov and Roxana Dumitrescu).
