Professor Nikos A. Aspragathos leads the Robotics Group Mechanical and Aeronautics Engineering Department, University of Patras. Electrical Engineering degree (1975) and PhD (1982) from the School of Electrical Engineering, University of Patras, Greece. He joined Greek industrial companies as a construction and maintenance Engineer (1976-1980). In 1982, he was appointed Lecturer in Mechanical and Aeronautics Engineering Department, University of Patras. He was a visiting member of the staff in University of Newcastle (1983), UWIST, Cardiff (1987 to 1988), and CEA-LIST, Laboratoire de Robotique Interactive, Fontenay-aux-Roses, Paris (2011-2012). He gave invited lectures and seminars in well known universities and research institutes. He supervised seven finished PhD and a considerable number of fourth and final year student projects.He has published about 200 journal and conference papers and book chapters. He is a reviewer in about 30 Journals and more than 20 conferences. Member of the editorial board of the Mechatronics Journal, ISRN Robotics and International Journal of Automation, and Control. He joined more than 20 Scientific or Organizing committees of conferences and organized two national robotic conferences. Proposals reviewer or Jury member in Greece and aboard. Member of Advisory Group for New Robotics Engineering Book Series, ASME Press.
He has been and is currently involved in research projects and Networks of Excellence (NE) funded by Greek and European Union sources. In most of the projects and in the NE he was the leader of the University of Patras team.
He is a member of committees and boards in administrative, scientific and social entities and associations.
