CV

Robert Kirchner (*1981, Germany) studied Electrical Engineering at the Technische Universität Dresden (Germany) and Chalmers University of Technology (Sweden) from 2001 until 2007 with a special focus on Electronics Packaging, Biomedical Engineering and Microsystems Technology. In his PhD he developed an UV-assisted nanoimprint lithography (UV-NIL) process for planar photonic biosensors until 2011. Until 2012 he holds a PostDoc position at the TU Dresden to transfer this UV-NIL process as pre-production technology to the Fraunhofer Institute of Photonic Microsystems (IPMS) in Dresden. Since 2013 he holds a PostDoc position at the Paul Scherrer Institut within the Laboratory for Micro- and Nanotechnology. His main focus is on new 3D lithography approaches using electron beam grayscale and two-photon patterning. His current interest lies in exploitation of the interaction of polymers with electrons and high energy photons for micro-nano-fabrication. He realized numerous industrial projects for optical und bio-inspired applications.
