After a PhD in Physics at Dortmund University in 1989 he joined the University of Augsburg to establish a research team for ion beam physics, electron microscopy and nanomaterials. After “habilitation” in 2000 he became academic director and was appointed professor in Augsburg in 2008.The radiation damage of semiconductors, the formation of buried elemental and compound layers by ion beam synthesis and radiation effects in nanostructures were among the research topics at that time. With his research team and partners from industries he developed patents on the formation and processing of SiC layers. Extended research stays lead him to Hong Kong, Nagasaki and Madrid.
In 2009 he became professor at Paderborn University, where he is heading a group for Nanopatterning, Nanoanalysis and Photonic Materials, forming an interface between physics, chemistry and mechanical engineering. He is, in parallel, guest professor at the Ruhr-University in Bochum (Germany), on the board of directors of the Centre of Optoelectronics and Photonics Paderborn CeOPP, founding member and CEO of the Institute of Ultra-Light Weight Construction with Hybrid Systems ILH in Paderborn, he is serving the European Materials Research Society EMRS (since 1999, executive committee and scientific council) and he is member of the editorial board of Springer Nature Applied Sciences. For EMRS, MRS (USA) and other organizations he (co-)organized more than 12 international conferences/symposia and he (co-)authored more than 300 papers, book chapters and conference contributions. His present research focus is on self-assembly techniques for the large-area nanopatterning of semiconductors and on advanced transmission electron microscopy.
