Astrophysik), Garching, Germany, in the period 1984-1995 during which he obtained his Master degree and his Ph.D. in Theoretical Physics at Munich University (LMU) (1988). His research was focussed on cosmological structure formation theories, where the heart of this work was defined within a project of the DFG (German Science Foundation) leading to his Habilitation degree in Astronomy at the LMU (1994). In 1995 he obtained the degree Privatdozent at LMU. Since then he worked as Research Associate at LMU and TUM (Technical University Munich), and as a Lecturer at LMU. During that time he was leading a research group at the LMU on morphological statistics of cosmic structure together with Herbert Wagner. From 1998 until now he took several long-term visiting positions as Associated Member of Personnel at CERN, Geneva, as Tomalla Visiting Professor at University of Geneva, as Center of Excellence Researcher at the National Astronomical Observatory in Tokyo, and as Monkasho Invited Professor at the University of Tokyo, during which he also worked as Visiting Professor at Tohoku University in Sendai, and the Tokyo Institute of Technology. During the summer term 2006 he took a temporary Chair position at Bielefeld University. From September 2007, he is Staff Member at the Observatory of Lyon, and Professor of Cosmology at University Lyon 1. He received an ERC advanced Grant in the period 2017-2023.
