Group Leader

Prof. Sergio Valenzuela obtained his PhD in physics in 2001 at the Universidad de Buenos Aires (Argentina) and held research positions at Harvard University and the Massachusetts Institute of Technology (MIT). Since July 2008 Prof. Valenzuela has been an ICREA research professor and leader of the ICN2 Physics and Engineering of Nanoelectronic Devices Group.

His research is focused on the unique properties of materials with nanoscale dimensions, motivated by both their intrinsic scientific interest and their potential for advanced electronic applications. His work encompasses spintronics, quantum computation with superconducting circuits and nanoelectromechanical systems (NEMS). Together with his collaborators, he has pioneered the use of non-local devices to study the spin Hall effect of thermopiles to isolate the magnon drag in ferromagnetic materials, and implemented novel qubit control and spectroscopy methods.

Prof. Valenzuela was awarded the 2001 Giambiagi prize and the 2009 IUPAP Young Scientist Prize in Magnetism for his contributions to the field of spintronics, as well as an ERC Starting Grant in 2012. He has authored over 50 articles (Nature, Science, Reviews of Modern Physics, Nature Materials, Nature Physics, Physical Review Letters, among others), three patents, and five books or book chapters.
