Dr. Juan F. Sierra received his bachelor in physics from Universidad Complutense de Madrid (2003) and his Ph.D. from Universidad Autónoma de Madrid (2008). During the period 2009-2012 he worked at CEA-Grenoble, first as a CNRS postdoctoral fellow and then awarded Marie Curie IEF. His research was devoted to studying spin transfer torque phenomena in nanoscale magnetic tunnel junctions. Since 2012 he works in the group of Prof. Sergio O. Valenzuela at the ICN2. The primary scientific aim of his current research consists in developing new device concepts and demonstrating their potential for spin manipulation and thermoelectric energy harvesting using two dimensional materials.
