Dr. Patrick Ruther

Dr. Patrick Ruther studied physics (University of Konstanz, Germany), and received his PhD in Mechanical Engineering from the University of Karlsruhe, Germany on a LIGA-based micro-mechanical test-setup for micro-samples. During his postdoctoral fellowship (1996 to 1998) at the Institute of Microstructure Technology, Research Center Karlsruhe (now KIT) he was responsible for industrial projects targeting micro-optical LIGA components such as multi-fibre connectors for telecommunication and optical distance sensors for robot applications. Since October 1998, Patrick Ruther is senior scientist and group leader at the Microsystem Materials Laboratory (Prof. Dr. O. Paul), Department of Microsystems Engineering (IMTEK), University of Freiburg.
