Daniel Erni was born in Lugano, Switzerland, in 1961. He received an El.-Ing. HTL degree from the University of Applied Sciences in Rapperswil (HSR) in 1986, and a Dipl. El.-Ing. degree from ETH Zürich in 1990, both in electrical engineering. Since 1990 he has been working at the Laboratory for Electromagnetic Fields and Microwave Electronics, ETH Zürich, on nonlinear wave propagation, laser diode modeling (multi-section DFB and DBR lasers, VCSELs), computational electromagnetics/computational optics and on the design of non-periodic optical waveguide gratings e.g. by means of evolutionary algorithms. He got a Ph.D. degree in 1996 for the investigation of non-periodic waveguide gratings and non-periodic coupled cavity laser concepts. His current research includes advanced data transmission schemes in board-level optical interconnects, such as optical MIMO systems as well as optical on-chip interconnects. The latter is part of a further research focus encompassing ultra-dense integrated optics, nanophotonics, plasmonics and quantum optics. On the system level Dr. Erni has pioneered the introduction of numerical structural optimization into integrated optics device design. In 2001 he has been awarded the 2000 Outstanding Journal Paper Award by the Applied Computational Electromagnetics Society for a contribution on the application of evolutionary optimization algorithms in computational optics. Further research interests include science and technology studies (STS) as well as the history and philosophy of science with a distinct focus on the epistemology in engineering sciences. From 1995-2006 Dr. Erni has been the founder and head of the Communication Photonics Group at ETH Zürich. Since Oct. 2006 he is a full professor for General and Theoretical Electrical Engineering at the University of Duisburg-Essen, Germany. He is a Fellow of the Electromagnetics Academy and an associated member of the Swiss Electromagnetics Research Centre (serec), as well as a member of the Swiss Physical Society (SPS), of the German Physical Society (DPG), of the Optical Society of America (OSA), and of the IEEE.
