Dr. Busch received his Diplom in Physics from the Universität Karlsruhe, Germany, with a thesis on the theory of shift currents in the photogalvanic effect. He received his Doctorate in Physics from the University of Karlsruhe, where a substantial part of his dissertation has been carried out at Iowa State University, Ames, IA, with a scholarship of the German Academic Exchange Service (DAAD). Together with Costas Soukoulis, he developed a new effective medium theory that facilitates a quantitative description of classical wave propagation in random media which has been extensively applied in studies of light diffusion. From 1997 to 1999 he worked as a postdoctoral fellow of the German Research Foundation (DFG) at the University of Toronto on the optical properties of Photonic Crystals. Together with Sajeev John he co-invented the concept of tunable Photonic Crystals structures. From 2000 to 2003 he headed a junior research group (Emmy-Noether fellowship of the DFG) at the Institut für Theorie der Kondensierten Materie (lead by Peter Wölfle) of the Universität Karlsruhe and worked on wave propagation and light-matter interaction in micro- and nano-structured materials. In particular, he introduced the Wannier function approach to the modelling of Photonic Crystals. In 2001 he became a founding member, principal investigator, and spokesperson for Research Area A: Nano-Photonics of the Center for Functional Nanostructures (CFN) of the DFG at the Universität Karlsruhe. He joined UCF in 2004 and helds a joint appointment between the Department of Physics and the School of Optics: CREOL & FPCE. In 2005 he returned to Universitaet Karlsruhe, Institut fuer Theoretische Festkoerperphysik.
