Hugo Bailly

Affiliate Fellow

Hugo Bailly

Hugo studies the interaction between climate, financial and economic risks. His work aims to understand how sector-specific climate or financial risks can spread in the economic fabric of a region via the interrelationships between sectors. This analysis relies on the inclusion of multi-sectoral dynamics within out-of-equilibrium macroeconomic models.

Clémence Démurger


Clémence is a research fellow at the Environmental Justice Program, studying the material sustainability of the economy. Using an assessment model of the economy and resources, she tries to understand the interactions between economic dynamics and resource depletion, and to provide insight on most adapted policies and development scenarios.

Previously, her research was shared between environmental economics (aiming at assessing the impact of damage inequalities on optimal climate policy) and philosophy (drawing links between continental phenomenology and the lack of realism of the concept of homo economicus).

Keywords: Natural resources, Sustainability, Stock-flow consistent models, Ecological macroeconomics

Degrees: Master’s degree in Economics (Paris-1 Panthéon Sorbonne University), Master’s degree in Philosophy (Ecole Normale Supérieure de Paris)

Loïc Giaccone


Loic Giaccone

Loïc is preparing a Ph.D. on the interactions between climate change and economic inequality, supervised by Dr. Gaël Giraud. He analyzes how, in different transition scenarios, inequalities are changing, using integrated assessment models developed by the EJP. These models will simulate important feedback on societies: climate change impacts, economic impacts, and resource scarcities. The goal is to identify which trajectories, and the associated policies, that allow both low climate outcomes and inequality reduction.

Misgana Elias Kallore


Misgana Kallore

Misgana works on a Project- EcoCampuses – that intends to study what takes for Campuses to transform themselves into an eco-campus. The project begins by proposing a unifying or common definition of what eco-campus means to set a standard by reviewing concepts, experiences, practices, and brainstorming. Curriculum transformation and pedagogical approach as a means to “just transition” for the societal and behavioral shifts are key points the study will look into. Cases of campuses in different countries will be assessed while demonstrating the practical transformation process with Jesuit Universities.

Simon Lebastard

Student Research Assistant

Environmental Economics, Energy Economics, Computational and Statistical Methods, Data Science

Simon is a Ph.D. student in Environmental Economics at Georgetown University, working on studying interactions of energy and environmental resources with macroeconomic variables. These building models put these physical constraints at their core and offer better insight into what policies would be best to tackle environmental emergencies through policies that put a prime consideration on social justice. My thesis is supervised by Dr. Gael Giraud, Director of the Environmental Justice Program.

Previously, his research focused on the intersection of machine-learning and neuroscience – more specifically in learning theory, continual learning, and Bayesian statistics, and thus aims to contribute to some empirical aspects of economics. He also studied the application of data science to challenges in the public sector: he worked as a “Common Good Entrepreneur” (Entrepreneur d’Intérêt Général) on applying data science for innovation and public policy evaluation.

Frédéric Mortier 

Associate Research Professor

Frédéric Mortier is a senior statistician working for the last 20 years on various aspects of applied statistics, with a focus on the development and the application of modern statistical tools in ecology, quantitative population genetics, and macroeconomy. His statistical expertise includes multivariate models taking into account spatial dependencies in large datasets, variable selection, mixture models, Bayesian inference and machine learning. In particular, he has used these models to understand the impact of global changes on tropical ecosystems.


Mlondi Ndovela

Affiliate Fellow

Mlondi Ndovela smiling.

Never get cold feet when the pressure comes.

Mlondi is working on his Ph.D. thesis entitled Macroeconomic implications of energy transition in South Africa: Results from an integrated non-equilibrium economy-climate model. The study is part of the joint project between the Centre for Sustainability Transition and the Environmental Justice Program. His Ph.D. study addresses the absence of an integrated non-equilibrium economy-climate model for South Africa. Furthermore, there is a conspicuous non-linkage between the energy transition and macro-economic factors from various models developed by Applied Development Research Solutions (ADRS), Meridian Economics, University of Cape Town (UCT), and the Council for Scientific and Industrial Research (CSIR). To address this problem, the study aims to use an INEEC model developed in partnership with GTU in order to simulate BAU and alternative scenarios for South Africa’s energy transition within the wider macro-economic context.

Grégoire Noël


Grégoire’s researches aim at providing a formal framework embedding macroeconomics within a thermodynamical realm. Economies are complex, open metabolisms perpetually trading energy and matter flows with the environment to sustain themselves and grow in mass and complexity. Crucially though, the environment is finite and endures the entropic pressure that the economies exert on it. Reconceptualizing economies as far-from-equilibrium dissipative structures shall help address the ecological sustainability of economic prosperity and development.

Peter Rožič

Associate Research Professor

Peter joins the Georgetown Environmental Justice Program (EJP) during the Spring 2023 semester before moving to Oxford as Director Designate of the Global Integral Ecology Research Network at the Laudato Si Research Institute (LSRI), Campion Hall, University of Oxford.

At Georgetown EJP, Peter embarks upon researching collaborative approaches to innovate and sustain global strategic partnerships to further enable ecological and societal change through the paradigm of “integral ecology” by bringing together academia, policy, and action.

He is passionate about forming leaders through innovative, impactful learning and networking processes. He has created programs that have helped hundreds of top talents secure positions in various institutions worldwide. He has a history of leading international teams and boards within fast-paced educational environments that include leadership, teaching, and innovation-in-education experience. He has published 17 peer-reviewed articles, 5 edited-volume chapters, and 180+ essays/pieces. Additionally, he has collaborated with EU-level policy and campaign leaders to deliver integrated advocacy.

Pauline Smith

Postdoctoral Researcher

Pauline Smith.

Pauline’s work aims to build a better understanding of our relationship to nature, and create policy recommendations for campuses that want to foster their students relationship with nature. Feeling connected with nature can be a powerful drive towards a more sustainable lifestyle as well as a source of happiness, but we are not sure how to foster this feeling in adults, or what the cognitive basis of this connectedness are. Pauline investigates these questions by exploring the role of attention built through habits, as well as drawing insights from subjective accounts of people’s relationship with the natural world.

Paul Valcke

Postdoctoral Researcher

Paul Valcke smiling in front of trees.

Paul’s work aims at the creation of economical models that can take into account the dynamics of inequalities in a society. This work is integrated in a larger approach of economical models that can take into account spatial effects, energy, resources, climate and biodiversity. His work is based on dynamical models from economy, but also from statistical physics, theoretical ecology, and morphogenesis.

Weiye Zhu

Student Research Assistant

Weiye is born and raised in Xi’an, China, a historic city that retains more of its ancient character and atmosphere than Beijing. He graduated from the University of Miami with a degree in B.S. in Mathematical Statistics and Economics in 2022, and he is currently a Master’s student in Data Science & Analytics at Georgetown University.

Weiye always had a passion for statistics and economics and hoped to utilize the knowledge and skills to help leaders in business or government organizations make better decisions. He is a Research Assistant at the Environmental Justice Program, studying how different variables and factors affect the equilibrium and their trajectories in the economic models.

Hugo Martin

Hugo Martin smiling in front of a snowy landscape.

Hugo’s research aims to integrate the impacts of human societies on the earth’s climate by linking macroeconomic models to climate models. This interaction is crucial for the understanding of global warming. Indeed, depending on economic scenarios, CO2 emissions can change dramatically, always increasing with global production. In the face of global warming, international economic policies must be carefully chosen. Their objective must be the perfect control of CO2 emissions as well as the improvement of social progress. Therefore, determining precisely what changes would be induced on the earth’s climate by CO2 emissions is definitely a cornerstone of any rigorous planning of economic policies. Numerical simulations provide a useful toolbox for testing any economic strategy and directly observing their consequences on our environment.

Timothée Nicolas

Timothée Nicolas.

Timothée works in close collaboration with Hugo Martin on macroeconomic simulations, considering macroeconomy as a dynamic system in interaction with climate, which is described by a simplified GCM model. The aim is to understand how climate change can affect the economy, first at a global level, and eventually at the regional level, and how cuts in CO2 emissions might preserve the economy.

Strength and Light

Maria’s work aims to create a space dedicated to young Economists who want to build on the work developed around the Economy of Francesco to build a World in Common. In this space, young economists will be able to discern how to reform the world’s economy and develop their projects and research in this field. This way, they will be able to become actors able to ensure the ecological and social reconstruction of our societies by overtaking the limits of conventional economics. It will be a place to exchange ideas for young economists, social organizations, and actors of civil society who want to fight climate change through this framework.

Daniel Presta

Daniel is a PhD student in the McMaster University School of Computational Science and Engineering, studying under the supervision of Dr. Matheus Grasselli, Professor and Deputy Provost at McMaster University. His research focuses on uncertainty and sensitivity analysis of macroeconomic and climate-economic models, and attempts to determine the economic parameters most responsible for convergence to various economic steady-states through stability analysis, statistical analysis, and machine learning techniques.

Furthermore, he has worked on extensions to the base Goodwin-Keen model, with most of his recent work centered on adding fiscal and monetary policy components to the original framework.  He aims to study a series of “green” fiscal and monetary policy measures, with the intention of investigating the effects of climate change and decarbonization on the stability of economic systems.

At Georgetown, Daniel is a member of the team dedicated to building a comprehensive climate-economic model for South Africa. He analyzes data to estimate key economic parameters, and will explore the stability and sensitivity of the model using statistical and machine learning methods.

Degrees: M.Sc. in Mathematics, McMaster University; (Honours) B.Sc. in Mathematics and Statistics, McMaster University

Camille Souffron 

Student at the ENS Ulm (Paris), Camille’s research focuses on dynamic non-linear and non-equilibrium economic modeling in collaboration with Paul Valcke with the objective of integrating emergence, complexity and multisectorial in macroeconomic models, notably for the ecological transition and in dialogue with traditional economic models. Another part of his work deals more broadly with the epistemology of economics and the history of its thought under a critical and peirastic prism. Also trained in law, he is similarly interested in economic public policy, including proposals to cancel public debts on central banks’ balance sheets and the doctrine of odious debt. He teaches environmental economics at the ENS Ulm.

Keywords: complexity and non-equilibrium macroeconomics and modeling, ecological economics, law and public debt, epistemology


Mark Swilling

Mark Swilling smiling in a natural setting.

Mark’s research over the past three decades has addressed many issues, but the core focus has been transition. During the 1980s and early 1990s, his focus was on the transitions to democracy that swept across Latin America, Southern Europe, Eastern Europe and then Africa in the 1990s (including SA in 1994). During the 1990s his focus was urban transition, with special reference to the building of the Lynedoch EcoVillage from the late 1990s. From the early 2000s, his focus has been on sustainability transitions culminating in various publications including his co-authored book Just Transitions in an Unfair World (2012). Drawing on many different intellectual influences (Dutch transition theory, African philosophy, Roberto Unger’s theory of change, long-wave thinking, state theory (especially Jessop) and anticipatory thinking, Mark’s latest book (The Age of Sustainability) provides the basis for his work at GEJP. He intends to focus on energy transition and the collibratory governance of non-equilibrium economic dynamics.
