Fields of expertise
BiographyGuillermo Villanueva is an Associate Professor at the Ecole Polytechnique Federale de Lausane (EPFL), Switzerland, in the Mechanical Engineering Institute (IGM). Before joining EPFL he was a Marie Curie post-doctoral scholar at DTU (Denmark) and Caltech (California, US); and before a post-doc at EPFL-LMIS1. He received his M.Sc. in Physics in Zaragoza (Spain) and his PhD from the UAB in Barcelona (Spain).
Since the start of his PhD (2002), Prof. Villanueva has been active in the fields of NEMS/MEMS for sensing, having expertise from the design and fabrication to the characterization and applicability. He has co-authored more than 100 papers in peer-reviewed journals and more than 130 contributions to international conferences. He is serving, or has served, on the program committees of IEEE-NEMS, IEEE-Sensors, MNE, IEEE-FCS, Transducers and IEEE-MEMS. He is editor in chief of the Physical Sensors section of MDPI Sensors. He has co-organized MNE2014, SNC2015, the short courses at Transducers 2019 and the 16th International Workshop on Nanomechanical Sensors (NMC2019).
