I studied biology and chemistry at the university of Giessen. From 1977-1986 I was scientific assistant at the RWTH Aachen (University of Technology) teaching general biology for students of medicine and investigating the life cycles of European tettigoniids. Later I contributed to a research project on the impact of agricultural practice on the arthropod fauna by the LÖBF NRW. From 1990-1993 I established the entomology field course within the diploma course in Environmental Sciences at the Swiss Federal Institute of Technology Zurich. Since 1994 I carried out several projects on systematics, bioacoustics and biodiversity informatics at the Research Institute Senckenberg in Frankfurt/Main and since 2000 at the Zoological Research Institute and Museum Alexander Koenig (ZFMK) in Bonn. Current emphasis of my work is on biodiversity, systematics and evolution of Orthoptera of the Indo-malayan and Indo-australian regions.
