Denis Gillet received the Diploma in Electrical Engineering from the Swiss Federal Institute of Technology in Lausanne (EPFL) in 1988, and the Ph.D. degree in Information Systems also from the EPFL in 1995. During 1992 he was appointed as Research Fellow at the Information Systems Laboratory of Stanford University in the United States. He is currently Maître d’enseignement et de recherche at the EPFL School of Engineering, where he leads the React multi-disciplinary research group. His current research interests include Technologies Enhanced Learning (TEL), Human Computer Interaction (HCI), Human Devices Interaction (HDI) and Optimal Coordination of Complex and Distributed Systems. During the academic year 2005-2006 he was on sabbatical leave as Visiting Scholar at the Faculty of Engineering, Chinese University of Hong Kong. Between 2011 and 2013, he was Guest Professor at the School of Software Engineering, Tongji University. Denis Gillet is affiliated at EPFL with the Transportation Center and the Center for Digital Education.
Nilson Marcos Dias Garcia he has a degree in Physics from Universidade Federal do Paraná, a degree in Operation Engineering – Civil Construction, from Centro Federal de Educação Tecnológica do Paraná, a Master in Science Teaching – physical modality and a Doctor in Education, both from Universidade de São Paulo. He has been a professor of physics in high school in public and private institutions. In 1976 he joined the then CEFET-PR (currently UTFPR) as a professor of physics in the academic physics department and from 1997 he also began to act as professor and researcher in the postgraduate program in technology and society, at the same University, where he guides research on issues related to professional education and worker training. He is also an accredited professor, since 2003, in the postgraduate program in education of the Universidade Federal do Paraná where he guides research on teaching physics. He is one of the leaders of the group of studies and research in teaching physics (GEPEF). In addition to teaching and research, he has been head of the academic physics department and participant in several collegiate bodies, including the university council. Participates in the Brazilian Physics Society: he was a member of the teaching commission; he served on the board as General-Secretary, and is currently a member of the research area committee in physics teaching and an elected alternate advisor to the Sociedade Brasileira de Física. He has been coordinator of the CERN Physics School since 2009. His research interests are focused on the nature and importance of school knowledge and textbooks, mainly in physics, for regular schools and for professional training.
