Personal details

MSc, PhD

I am a Belgian engineer (U. Liege, 1967). I turned toward theoretical studies of materials and condensed matter for my M.Sc. (Brown U., 1970) and toward statistical physics for my PhD (Temple U., 1973). Advisors for the final thesis were R Simon, A. Baratoff, and K. Kawasaki, respectively. Thereafter, I have been applying statistical physics ideas and methods in various fields encompassing biophysics, financial and econo-physics, meteorology, linguistics, socio-physics, and many other non-equilibrium time-dependent systems, beside pursuing investigations on condensed matter, e.g. on liquids, alloys, magnets, ceramics, or superconductors.

After some visiting professorship, at the Freie Univ. Berlin, I returned to the University of Liege, where I spent my whole career, mainly teaching and performing some research on materials and in statistical physics. I founded the SUPRAS "horizontal" group of scientists belonging to various ULG laboratories (physics, chemistry, engineering) with fundamental or applied science interests on ceramics superconductors and magnetic materials. The research group culminated in a FNRS recognized Center of Excellence, SUPRATECS. In parallel, I initiated the GRASP, later on reforming part of the group to become GRAPES (Group of Researchers for Applications of Physics in Economy and Sociology). Since Nov. 2014, I have held a part-time chair at the School of Business, College of Social Science, Arts and Humanities, at the University of Leicester.

I have contributed greatly to statistical mechanics theory through studying various disordered systems, which can be described along fractal and multi-fractal ideas. I have been much interested in describing non-linear and out-of-equilibrium phenomena, in classical and so called exotic physics, through mathematical formalisms and simulation works. My work in econo-physics and socio-physics is widely respected.

I have in the order of 600 publications, in peer review journals and as peer review published communications at scientific meetings, with more than 300 different coauthors; I have edited 9 books, organised many international conferences, directed many graduate student theses, presented many scientific contributions at meetings or gave seminars, and taught in many "summer/winter schools". I am or have been a member of the editorial board of various journals, and very often chosen as a reviewer. My Hirsch index is greater than 40.

I have a widely open interest in interdisciplinary research and have a well known track for research project management or leadership. I have been taken as an expert for many projects by various financially granting bodies, in Europe and USA, and been recognised through several honoring distinctions.


Econophysics, sociophysics, nonlinear dynamics, nonequilibrium systems, networks, phase transitions, growth (and decay) models, fractals, scientometrics, statistical physics, materials sciences and applied mathematics.
