Fondation des Sciences de la Modélisation

Friday, January 23rd 2026, from 2:00 p.m. to 5:00 p.m., in Cergy.

Room C443, 4th floor, Chênes1

The workshop aims at fostering an interaction between students and more senior researchers in the fields of physics, computer science, economics and mathematics. Prsenters should prepare a short (30 minutes) exposition of their research with the goal of making the research material acessible to a non expert audience, and, if possible, suggest links between their research and research in other fields that use scientific modeling methods.

5th International Conference on Development Economics (ICDE 2025) 

Dates and location In Nanterre, France, on July 2-4, 2025 at Université Paris Nanterre.  

Short description:   ICDE 2025 convened scholars, policymakers, and practitioners to tackle current development challenges. Plenaries examined development finance, humanitarian medicine’s evolution, taxation in MICs, and African state capacity/innovation.  
A core message: strong, legitimate institutions are the bedrock of sustainable development.  
The conference emphasized shifting from traditional aid to co-financed, context-specific partnerships grounded in justice, trust, and equity.

Retour sur la conférence:  

 ICDE 2025 delivered three days of rigorous debate on inclusive, evidence-based development.  
Leonard Wantchekon (Princeton) showed how innovation and research—grounded in history, democracy, and human capital—can build state capacity and accelerate sustainable development in Africa.  
Dina Pomeranz (Zurich) unpacked the administrative and political trade-offs of expanding tax capacity, arguing that fair, efficient taxation is central to state-building, equity, and financing development.  
A roundtable with Alexandre Kolev underscored that social protection is not a cost but a strategic investment in poverty reduction and societal resilience.

AICC 2025 

Dates and location In Lausanne, Switzerland, on July 4-5, 2025.  

Short description:   On 4–5 June 2025, the third international conference Action versus Inaction facing Climate Change (AICC3) was held at EPFL Lausanne. Participants emphasized that while the tools to address climate change are already available, urgent and coordinated action is required. Key priorities included phasing out fossil fuels, scaling up renewable energy, and building resilient cities and infrastructures, particularly in the Global South.

Retour sur la conférence:  

Held on 4–5 June 2025 at EPFL Lausanne, the Third International Conference on Action versus Inaction Facing Climate Change (AICC3) gathered researchers, policy-makers, and civil society to discuss urgent responses to the climate crisis. The central message was clear: solutions already exist — the real challenge is implementation.  

Key priorities identified included accelerating the phase-out of fossil fuels through scaled-up renewable investments, strengthening urban and infrastructure resilience to extreme weather, and advancing mobility transitions beyond car dependency. Participants also emphasized the crucial role of human behaviour, psychology, and social norms in shaping effective policies. Finally, justice and equity were underlined as essential to ensure legitimacy and solidarity, particularly given the disproportionate impacts on the Global South.  

AICC3 concluded with a strong call for political will, international cooperation, and shared responsibility to translate knowledge into action.

Non-stationarity and Statistics for EEG conference 

 Dates and location: In Nanterre, France, on 4–5 September 2025  

 Program: https://stateeg.sciencesconf.org/program?lang=en  

 Short description: The international conference Non-stationarity and Statistics for EEG brought together statisticians, neuroscientists, linguists, and medical researchers to tackle the challenges of analyzing time-varying EEG signals. Topics ranged from Bayesian methods, entropy-based clustering, and change-point detection to language prediction, dementia, neonatal care, epilepsy, and neurodegenerative monitoring. Advances in brain–computer interfaces and machine learning for biosignals were also showcased.   

Conference Highlights  

• Language & Cognition: Arista showed EEG evidence of predictive mechanisms in spoken language; Heidlmayr highlighted early language impairments in dementia.  

• Clinical Applications: Dollé advanced neonatal EEG analysis with U-Net segmentation; Papatzikis developed a neonatal qEEG pipeline for NICU interventions; Morain-Nicolier applied time–frequency methods for seizure detection.  

• Statistical Innovation: Dumont introduced entropy-based EEG segmentation; Freyermuth extended harmonizable time series modeling; Kirch developed efficient change-point detection methods.  

• Machine Learning & Biosignals: Dudek demonstrated person identification from cyclostationary ECG features; Gnassounou proposed Optimal Transport-based normalization for cross-subject EEG data.  

• Connectivity Modeling: Ombao presented frequency-specific lead–lag methods for neural oscillations.  

Key Takeaways  

• EEG reveals predictive and pathological mechanisms in language and cognition.  

• Novel methods enhance diagnosis in neonatal and epileptic EEG.  

• Statistical advances (entropy, harmonizable models, change-points) enrich signal analysis.  

• Machine learning approaches address variability and distribution shifts.  

• Frequency-specific modeling opens new perspectives in connectivity research.  

Perspectives  

The conference underscored the need to:  

• Develop models capturing temporal variability and inter-individual differences.  

• Improve reproducibility and bias control in high-dimensional data.  

• Foster collaboration among statisticians, neuroscientists, and clinicians.  

• Train young researchers at the theory–application interface.
