Mostapha Diss

Mostapha Diss is a University Professor and Director of CRESE (Research Center on Economic Strategies) at the University of Franche-Comté since January 2022. His primary institutional affiliation is with the Research Center on Economic Strategies (UR 3190), and he also maintains significant connections with the Africa Institute for Research in Economics and Social Sciences (AIRESS), Group for Analysis and Economic Theory Lyon - Saint-Etienne, and the Research Center in Economics and Management.

His research focuses on social choice theory, game theory, and political economy, with particular emphasis on voting systems, committee selection, and diversity constraints. His work bridges theoretical foundations with practical applications in electoral systems and decision-making processes, demonstrating how mathematical approaches can address complex social problems.

Professor Diss has published extensively in top journals including Journal of Mathematical Economics, International Journal of Game Theory, Review of Political Economy, and Social Choice and Welfare. His recent work (2024-2025) shows a strong trend toward integrating diversity constraints into cooperative game theory and voting systems, with significant contributions to understanding the impact of election closeness on voting paradoxes and developing new axiomatizations for diversity-aware game-theoretic solutions.

His notable scientific contributions include:

• New axiomatizations of the Diversity Owen and Shapley values
• Analysis of the effect of close elections on voting paradoxes
• Development of multiwinner election models with diversity constraints
• Studies on committee selection rules and their properties
• Applications of game theory to healthcare resource allocation

As Director of CRESE, Professor Diss has secured research funding that supports his work on voting theory and game theory applications. His leadership has strengthened the center's focus on mathematical approaches to social sciences, providing a collaborative environment for doctoral students and postdoctoral researchers working on theoretical and applied problems in economics and political science.

He leads the CRESE research center, which brings together researchers from various disciplines to address complex economic and social problems through quantitative methods and theoretical modeling. The center serves as a hub for innovative research at the intersection of mathematics, economics, and political science, with Professor Diss at the forefront of advancing theoretical foundations while maintaining relevance to real-world decision-making challenges.
