Luis Alexandre Rocha received the Degree in electronic engineering from the University of Minho, Guimarães, Portugal, in 2000 and the Ph.D. degree (cum laude) from the Delft University of Technology, Delft, The Netherlands, in 2005. He has been a MEMS Engineer at ASML Netherlands, in 2005 and an Assistant Professor
at the Faculty of Engineering, University of Porto, from 2006 to 2008. Since March 2008, he has been at the University of Minho as an Associate Professor. His research activities focus on the study and use of the nonlinear MEMS dynamic behavior and the fabrication of microsensors based in microtechnologies with special focus on high sensitivity inertial sensors.
