Curriculum Vitae

Jürgen Biela received the diploma (with honours) from the Friedrich-Alexander University in Erlangen, Germany in 2000 and the Ph.D. degree from ETH Zurich in 2005, all in electrical engineering. In the course of M.Sc. studies he dealt in particular with resonant DC-link inverters at the Strathclyde University, Scotland (term project) and the active control of series connected IGCTs at the Technical University of Munich (diploma thesis).  

He has worked at the research department of A&D Siemens, Germany, from 2000 to 2001, where he focused on inverters with very high switching frequencies, SiC components and EMC. In July 2002, he joined the Power Electronic Systems Laboratory (PES), ETH Zurich for working towards his Ph.D. degree and concentrated on the electromagnetic integration and optimization of resonant converter systems. From 2006 to 2007 he was a Post-Doctoral Fellow and from 2007 to 2008 a Research Associate with PES and has been a guest researcher at the Tokyo Institute of Technology, Japan. From January 2009 to July 2010 he is a Senior Scientist at PES, ETH Zurich, and is involved in teaching graduate and undergraduate courses, co-supervising Ph.D. students and leading industry research projects. Since August, 2010 he is Associate Professor and Head of the Laboratory for High Power Electronic Systems at the ETH Zurich. 

His current research interest include multi-domain modelling, design and optimization of power electronic systems, in particular systems for future energy distribution and pulsed power applications, advanced medium voltage power electronic systems based on novel semiconductor technologies, e.g. SiC and integrated passive components for ultra compact and ultra efficient high power converter systems. 

Dr. Biela has published more than 50 journal and conference paper, and holds 13 patents. He is a member of the IEEE and actively acting as reviewer for all leading power electronic journals and conferences.
