Denis Phan is a Post & Telecommunications Administrator, Doctor in Economics, CNRS Senior Research Engineer at the GEMAS (Groupe d'étude des Méthodes de l'Analyse Sociologique, CNRS & Université Paris IV Sorbonne). His previous position was Senior Researcher CREM (2004-2006) and Associate Professor in Economics at ENST de Bretagne (1993-2006). Corresponding research interests was in the economics of telecommunications, the software industry and regulation. Denis Phan has published papers and various books in this field (TIC papers). Since 2000 his main research interest have been cognitive and computational economics & social sciences (ACE, cognitive economics and complex systems papers).

In the field of computational economics, Together with Antoine Beugnard, a computer scientist, Denis Phan built Moduleco, a modular multi-agent platform designed to simulate markets, organisations, social phenomena and population dynamics. This software is actually maintained at the University of Manchester (Computer Science Department) by Gilles Daniel. In an endeavour to unify existing agent-based platforms, Moduleco becomes a MadKit plugin by may, 2004, in cooperation with Jacques Ferber. Others works include emergence in artificial society in co-operation with Jean Louis Dessalles.

In the field of cognitive economics and complex systems, Denis Phan works in co-operation with physicists Jean Pierre Nadal and Mirta Gordon as an associate member of CENECC : CENtre d'Etudes des systèmes Complexes et de la Cognition (Center for the Study of Complex Systems and Cognition) at the ENS. Denis Phan Jean Pierre Nadal and Mirta Gordon work also with economist Roger Waldeck on the emergence of cooperation in communities.

Denis Phan has recently organized three main researchers school in the field of complex system dynamics & multi-agent system applied to Social and Human Science (SHS): Agay 2004, together with Jean Pierre Nadal and Gérard Weisbuch; Porquerolles 2005, together with Frederic Amblard and Nils Ferrand, and LaLonde 2007, together with Frederic Amblard, Arnaud Banos, Anne Bretagnolle, Eric Darmon, Eric Daude, Enrico Scalas and Celine Vacchiani-Marcuzzo. From This schools, we published introductory books on MAS modeling and simulation in Human and Social Sciences. One in French (Amblard, Phan, 2006) at Hermes-Lavoisier and a partial but enhanced translation in English (Phan, Amblard, 2007) at The Bardwell Press, Oxford.

Since Januray, 2007 Denis Phan is head of the ANR-CORPUS project "Corpus of Ontologies for Multi-Agents Systems in Geography, Economics, Marketing and Sociology"   (COSMAGEMS). In this context, coauthorship include Jacques Ferber, Pierre Livet, Jean Pierre Müller,  Lena Sanders and Franck Varenne. Since 2009, he is member of the ABR-Syscom project "Urban Collective Dynamics: Individual and Spatial Heterogeneities (DyXi) coordinated by Jean Pierre Nadal
