Bruno Ullrich, Ph.D., Department of Physics & Astronomy, and Center for Photochemical Sciences

The undergraduate students in my laboratory are hands-on included in experiments with photonic devices. The main part of the work incorporates the investigation of thin-film semiconductor based all-optical devices solely driven by laser beams. Currently, I am advising two undergraduates working on such devices. The goal of the activities is to introduce the students to the scientific world by teaching them correct data acquisition and gain of knowledge by combining different experimental techniques. Specific attention is paid to strategies, which rule out experimental errors. Typically, I am mentor of 1-2 undergraduates per semester and two of them (Hans Miller and Ryan Konopinski) essentially contributed to the research output of my laboratory:
