dr. M. Muñoz Rojo (Miguel)

I received my PhD (2015) in Condensed Matter Physics & Nanotechnology from the Spanish National Research Council (CSIC) and M.S./B.S. in Physics from the Autonomous University of Madrid. I obtained a JAE pre-doctoral Fellowship from CSIC to study during my PhD how the reduction of dimensionality affects the transport properties of organic and inorganic thermoelectric materials. During this period of time, I carried out scientific stays at the Rensselaer Polytechnic Institute (New York, USA), the University of Bordeaux (France) and the University of California Berkeley (USA). In 2012, I participated in the 62nd Lindau Nobel Laureate Meeting in Physics after qualifying in an international competition among young talent scientists. From 2016 to 2018, I became a postdoctoral researcher at Stanford University, studying two dimensional (2D) materials and devices based on them for thermal, electrical, and thermoelectric applications. From 2018 to 2021 I was a Tenure Track Assistant Professor at Twente University. Since December 2021, I became senior researcher (tenured) at the National Research Council of Spain (CSIC) with double affiliation to the University of Twente as Associate Professor. My line of research focuses on thermal management, energy harvesting, nano- and micro-scale thermometry and thermal sensing.
