born 1958, graduated in general theoretical and practical material sience, surface and corrosion techniques at Friedrich - Alexander - University in Erlangen in 1984. From 1983 until 1986, research engineer at SIEMENS AG KWU for eddy current techniques. Since 1986 research engineer at SIEMENS AG KWU for ultrasonic techniques. The work is focused on optimization and development of automatic UT-Systems ( ALOK, PSCAN, TOMOSCAN, LSAFT, HOLO3000, PHASCAN ). Qualification of the systems and training of adequate personnel is also part of the work. In several qualification programs like IGSCC, PISC, NESC, VIP, PDI etc. and first field expierence the capability of the developments were demonstrated world wide. Since 1994 additionally, design and manufacturing of UT- and ET- probes (including Phased Array and EMAT ) became part of the workfield.
