Philippe Thévenaz was born in 1962 in Lausanne, Switzerland. He graduated from the Swiss Federal Institute of Technology Lausanne (EPFL, École polytechnique fédérale de Lausanne) in January 1986, with a diploma in microengineering. He then joined the Institute of Microtechnology (IMT, Institut de microtechnique) of the University of Neuchâtel, Switzerland, where he worked as research assistant and scientist, first in the domain of image processing (optical flow), then in the domain of speech processing (speech coding and speaker recognition). He obtained a Ph.D. in June 1993, with a thesis on the use of the linear prediction residue for text-independent speaker recognition. He then worked from 1994 to 1996 as a Visiting Fellow with the now defunct Biomedical Engineering and Instrumentation Program (BEIP), part of the now defunct National Center for Research Resources (NCRR, which was renamed National Center for Advancing Translational Sciences (NCATS) in 2012), National Institutes of Health (NIH), Bethesda MD, USA, where he developed research interests that include splines and multi-resolution signal representations, geometric image transformations, and biomedical image registration. In 1996, he became a Visiting Associate. In 1997, the BEIP was renamed the now defunct BioEngineering and Physical Science (BEPS), and was moved to the Office of Research Services, Office of the Director, NIH. In 1998, the BEPS was renamed the Division of BioEngineering and Physical Science (DBEPS). From 1998 to 2001, Dr. Thévenaz is with the Swiss Federal Institute of Technology Lausanne (EPFL, École polytechnique fédérale de Lausanne) as first assistant, in the now defunct Biomedical Imaging Group (BIG, Groupe d'imagerie biomédicale) of the now defunct Institute of Applied Optics (IOA, Institut d'optique appliquée) of the now defunct Department of Microengineering (DMT, Département de microtechnique). In 2001, the DMT was renamed the School of Engineering (STI, Sciences et techniques de l'ingénieur). From 2001 to 2002, the IOA has been renamed the now defunct-and-resurrected Institute of Imaging and Applied Optics (IOA, Imagerie et optique appliquée). In 2002, the BIG was renamed the Laboratory of Biomedical Imaging (LIB, Laboratoire d'imagere biomédicale). From 2002 to 2004, the IOA was renamed the now defunct Institute of Biomedical Imaging, Optics, and Engineering (BIO-E). In 2004, the BIO-E was renamed the now defunct Institute of Imaging and Applied Optics (IOA, Imagerie et optique biomédicale). In 2008, the IOA was disbanded, replaced by the Institute of Microtechnology (IMT, Institut de microtechnique). Since 2004, Dr. Thévenaz is associate editor for IEEE Transactions on Medical Imaging. Since 2007, Dr. Thévenaz is associate editor for The Open Electrical and Electronic Engineering Journal.
