My first contacts with computer applications in archaeology date back to an internship at the computer laboratory of the Rheinisches Landesmuseum in Bonn, Germany, and a subsequent student job at the lab while studying mathematics and computer science. After finishing my diploma thesis dealing with the rectification of archaeological aerial images, I got a permanent job at the lab in 1988. Due to some organisational changes I am now member of the services and publication department in the Rhineland Commission for Archaeological Monuments and Sites.

I also gave lectures on these subjects at Bonn and Cologne University and was invited to give talks in several European countries.
