Prof Dierolf came to Lehigh in 2000 with a Ph.D in Physics from the University of Utah, and a Habilitation from the University of Paderborn, Germany, He is the current Chair of the Physics Department and holds a joint appointment with the Materials Science Department. In 2008, he was a Visiting Mercator Professor at the University of Bonn. He is on the International Committees of both the International and the European Conference on Defect in Insulating Materials (ICDIM, EuroDIM). He has served as a Principal Editor for the Journal of Materials Research and has been Guest Editor for Optical Materials. His  research is focused on the optical spectroscopy and microscopy of insulating and semiconducting materials. His group  exploits  the wealth of information that can be obtained by combining high spatial resolution (down to 50nm) of a near field optical microscope or a SEM instrument with the structural and atomic scale information contained in excitation-emission data, cathodoluminescence and Raman spectra.
