About Me

I studied “Mineralogie” at the University of Münster (Diploma thesis in 1981), obtained a PhD in 1985 and turned in my “Habilitation Thesis” in 1990. During my PhD time I spent one year at the Institute of Meteoritics (Albuquerque, USA) and afterwards six months at the Max-Planck Institute for Chemistry in Mainz. Since 1986 I am scientist at the University of Münster. Currently I am working in the TRR 170 project B05 at the Institut für Planetologie.

My main research interests are

  • Formation and evolution of chondrites and their components
  • Brecciation and reaccretion on/of meteorite parent bodies
  • Early fluids and volatiles on Asteroids
  • Formation and evolution of differentiated meteorite parent bodies


1989: Victor-Moritz-Goldschmidt-Award of the German Mineralogical Society (DMG)
1993: Albert-Maucher-Award for Geosciences of the German Research Foundation (DFG)
1998: Fellow of the Meteoritical Society
2006: Asteroid 6757 “Addibischoff” named by the International Astronomical Union
2015: New mineral “Addibischoffite” named by the International Mineralogical Association (IMA)
