His current research focuses on color reproduction, spectral color prediction models, moiré imaging, and visual document security. Recent achievements include the PhotoProtect technology, which incorporates text as chromatic differences in order to protect identity photographs (Swiss driving license), microstructure imaging, which is used by railways companies (SNCF, RENFE) and festival organizers (Paleo) to print tickets at home and the band moire imaging technology for the protection of security documents.
Jürgen Brugger
I am a Professor of Microengineering and co-affiliated to Materials Science. Before joining EPFL I was at the MESA Research Institute of Nanotechnology at the University of Twente in the Netherlands, at the IBM Zurich Research Laboratory, and at the Hitachi Central Research Laboratory, in Tokyo, Japan. I received a Master in Physical-Electronics and a PhD degree from Neuchâtel University, Switzerland. Research in my laboratory focuses on various aspects of MEMS and Nanotechnology. My group contributes to the field at the fundamental level as well as in technological development, as demonstrated by the start-ups that spun off from the lab. In our research, key competences are in micro/nanofabrication, additive micro-manufacturing, new materials for MEMS, increasingly for wearable and biomedical applications. Together with my students and colleagues we published over 200 peer-refereed papers and I had the pleasure to supervise over 25 PhD students. Former students and postdocs have been successful in receiving awards and starting their own scientific careers. I am honoured for the appointment in 2016 as Fellow of the IEEE “For contributions to micro and nano manufacturing technology”. In 2017 my lab was awarded an ERC AdvG in the field of advanced micro-manufacturing.

To cite a few of his many initiatives: his active contribution to the holding of a high level Indo Swiss Workshop on Science & Technology at Bangalore in 2003; the setting up of ISJRP - the pilot project on bilateral partnership in S&T between Switzerland and India - in 2004; developing ISBRI (Indo-Swiss bilateral research initiative) in 2006; etc. He remained as the main coordinator of the Indo-Swiss Joint Research Program between the period covering the program's inception in 2004 until February 2011. He is currently responsible for developing academic and institutional relations with the universities in India and South-East Asian countries. He has been instrumental in helping to open up a range of opportunities to the EPFL students, such as, doing their "mobility" years at one of the IITs or, their final year major projects or internships at one of the Indian institutions/companies. Over a hundred EPFL students have benefited from these programs. He was instrumental in establishing Internship program with the aim of promoting an awareness of EPFL among the IIT students. This program has become very popular among the IIT and IIITA students with several hundreds of them having benefited from this program. He played a key role in the setting up of the EPFL-IIT Madras joint postgraduate course on "Technology and sustainable development" in 2000-01. He was the co-director of the last edition of the course which was held between January and April, 2008.
