This is an old revision of the document!
I am an Austrian mathematician and mathematical physicist. I work at the University of Vienna.
I was born in Berlin but I grew up mainly in France. I am married with Charlyne since 1970 (we met in Nice in 1969) and we have four children; Serge, Corinne, Samantha, and Sven. My mother was from Helsinki in Finland and my father from Vienna; he left Austria a few days before the Anschluss. My parents met in France while studying French at the University; they married after the war in the lovely city of Saint Tropez on the French Riviera. I grew up in Berlin, and at the age of 6 I moved to France, first to Nice and then to Paris. I got my “Baccalauréat” at the Lycée de Saint Cloud near Paris. I then went back to Nice to study mathematics. I got my PhD at the University of Nice in 1978 under the supervision of Jacques Chazarain. In 1992 I obtained a “Habilitation à Diriger des Recherches en Mathématiques Pures” at the University of Paris 6 under the mentorship of Jean Leray, who was to become a friend.

Broadly speaking my research interests lie in Analysis, Geometry, and their applications to mathematical physics. A more precise and technical definition of me as a mathematician would be “works in symplectic harmonic analysis”.
Some of my hobbies: epistemological and ontological questions in quantum mechanics. Dining out and enjoying good company.
