David Molinero was born in Barcelona (Spain), in 1979. He received his B.S. and M.S. degree in Electronic and Telecommunications and his Ph.D. degree in Electrical Engineering from the Universitat Politecnica de Catalunya (UPC), Barcelona (Spain) in 2004, 2006, and 2009. From 2002 to 2009 he was a member of the Micro and Nano technology group (MNT) at UPC, where he was involved in clean room fabrication and testing of a variety of semiconductor and MEMS devices. His PhD thesis was focused on MEMS fabrication and actuation mode improvements on RF-MEMS switches. In 2009, he joined the Department of Electrical Engineering at Lehigh University, Bethlehem, PA, USA, as a Post-Doctoral Research Associate. He was involved in DARPA programs to study RF MEMS switch reliability and linearity. In 2013, he left academia to join WiSpry, Inc., Irvine, CA, USA, as a Staff MEMS Characterization Engineer and in 2017 as a Principal MEMS Development Engineer, where his focus continues on MEMS switches improvements based on reliability, RF performance and nonlinearities. In 2021, he joined Skyworks Solutions in Irvine, CA, USA as a Senior Principal Development Engineer where he is responsible of R&D characterization and analysis of BAW technologies. In 2021, he also joined Chapman University as a part-time lecturer, where he teaches an introductory class about MEMS devices and applications. David Molinero has several publications in conferences and journal articles, as well as invited talks. He holds two patents. His research interests include RF MEMS mechanical switches/resonators and acoustic resonator devices (BAW/SAW).
