Biography
Joachim Piprek received his Ph.D. in physics from Humboldt University in Berlin, Germany. He worked in industry and academia on design, simulation, and analysis of semiconductor devices used in optoelectronics. He has taught graduate courses at universities in Germany, Sweden, and in the United States. Dr. Piprek has published five books, seven book chapters, and more than 200 journal and conference publications (h-index>45). He was founder and co-chair of the annual international conference on "Numerical Simulation of Optoelectronic Devices" (NUSOD) and he also chaired several SPIE conferences. Dr. Piprek also served as executive/associate editor of two research journals and was invited guest editor for various special journal issues on optoelectronic device simulation.
