I was born in December 1956 and live with my wife Martina and son Christian in Marburg, Germany. There I work at the Medical Faculty of the Philipps-University as a full-time professor and chair of the Department of Prosthodontics and Orofacial Pain. I have had a fascination for astronomy and space exploration since my childhood in the good old Apollo days. In my spare time I do such things as painting and astrophotography. I'm a contributor of the Apollo Lunar Surface Journal, co-editor of the Alan Bean Online Gallery (www.alanbeangallery.com). Mars-crossing asteroid 16724 was named after me.
