Francisco J. Arregui received the MS degree in Electrical Engineering from the Escuela Técnica Superior de Ingenieros Industriales, Tecnun-University of Navarra, San Sebastian in 1994 and the PhD degree from the Public University of Navarra, Pamplona, Spain in 2000 where he is currently a Full Professor. His academic teaching activity has been always focused on sensors, instrumentation, digital electronics and microprocessors. He was part of the team that fabricated the first optical fiber sensor by means of the layer-by-layer self-assembly method at Virginia Tech, Blacksburg, VA, USA, in 1998. He is the author of more than 300 scientific journal and conference publications, most of them related to optical fiber sensors based on nanostructured coatings. Francisco J. Arregui has been Founding Editor-in-Chief of “Journal of Sensors” as well as an Associate Editor of the Journals “IEEE Sensors Journal”, “Journal of Sensors” and “International Journal on Smart Sensing and Intelligent Systems”. Dr. Arregui regularly cooperates as evaluator for Science Agencies of different countries as well as participates in the Technical Program Committee of sensor-related conferences. He is also editor of the books “Sensors based on nanostructured materials” and “Optochemical Nanosensors” and co-founder of several technology companies, among them, Nadetech S.L.
