Born 1958, I am professor emeritus at the Université de Lorraine in Metz (France) and, since 2020, guest researcher at the University of Luxembourg, my home country. I obtained my Ph.D. (1984) and habilitation (1988) at the University of Karlsruhe (Germany) and was hired by the Université de Metz in 1995. From 2017-2020 I lectured at the University of Luxembourg, still being affiliated with the Université de Lorraine. My main interests lie in function theory, functional analysis, operator theory and point set topology. MR Author ID: 127275.
