I was born in Lyon, France, on March 1st 1946. I graduated from the Université Claude Bernard in
1968, while I was working as a teaching assistant at the E.C.A.M.. In 1969 I was awarded the
Agrégation in Physics. I taught for one year at Lycée La Martinière at Lyon, a preparatory class
for engineering schools while in the Graduate School of Theoretical Physics in Marseille.
In October 1970, I became Assistant Professor at the Université de Provence, Marseille, where I
stayed for twenty years, becoming eventually Full Professor in 1991. Throughout this period, I was
a member of the Center of Theoretical Physics of Marseille. I defended my Ph. D. thesis in June
1974. The subject was Quantum Field Theory in External Fields. My thesis advisor was Raymond
Stora, the physicist whose name is the "S" of the BRST transformation which occurs in nonabelian
gauge field theories.
I was trained at the University of Lausanne (The Physics Department is now transferred at the
EPFL), Switzerland, as a postdoc in 1974-75 with adviser Jean-Jacques Loeffel. After returning to
Marseille, I spent four months at the Z.I.F. Bielefeld, Germany, in 1976. I also visited the
I.H.É.S., Bures s/Yvette, France, between October 1979 and January 1980. There, I have had a
unique opportunity to work with Alain Connes. He was creating what became eventually the
Noncommutative Geometryfor which he was awarded the Fields Medal in 1982. It was during this very
exciting period that I started my present program of research on the Noncommutative Geometry of
Aperiodic Solids.
I became Associate Professor in 1980. During the eighties, I visited the U.S. numerous times: I
stayed for a year at Princeton as an Associate Professor in Physics and in Mathematics in
1983-84, and at Caltech for six months as a Visiting researcher in 1986. During this period, I was
the Graduate Coordinator of the Graduate School in Theoretical Physics, common to the Universities
of Aix-Marseille I & II, of Toulon and Nice from 1984 till 1990. Then, I spent the year 1990-91 in
Berlin at the Wissenschaftskolleg zu Berlin, just after the Berlin wall had collapsed: it gave me
a chance to teach a semester special course at the Humboldt University where Planck, Einstein and
Weïerstrass had taught in the past. I became an Associate Editor of the Review of Mathematical
Physics, during this period.
From 1991 till 2002, I was at the Université Paul Sabatier, Toulouse, where I created the Group of
Theoretical Physics. I was chairman of the Department of Physics from 1992 till 1996. From 1993
till 1999, I was the Chief Editor of the Annales de l'Institut Henri Poincaré (Theoretical
Physics). On January 1st 2000, this journal merged with Helvetica Physica Acta to become the
Annales Henri Poincaré, with Vincent Rivasseau as chief-editor. Since 1995, I have been a Senior
member of the Institut Universitaire de France. I resigned from being the head of the Toulouse
Group of Theoretical Physics in 2000 that permitted me to visit MSRI, Berkeley, in 2000-2001. I
spent the year 2001-02 in Paris at the École Polytechnique and the I.H.É.S. while joining the
Laboratoire Émile Picard, Department of Mathematics, Toulouse.
I moved to Atlanta GA on August 16, 2002, where I have been Full Professor at the Georgia
Institute of Technology, with a position in the School of Mathematics and in the School of Physics.
I also became Associate Editor of the Mathematical Physics Electronic Journal created by Giovanni
Gallavotti in 1995. In 2006 I became Associate Editor of the Journal of Noncommutative Geometry
newly created by Alain Connes.
