Oxide Nanophysics Group
Group Leader: Gustau Catalán
Group Leader
Prof. Gustau Catalán earned his degree in physics at the Universitat de Barcelona in 1997 and his PhD in physics at Queen’s University of Belfast in 2001. He then took research positions at the Institut Mediterrani d’Estudis Avançats (2002-2004), the Rijksuniversiteit Groningen (University of Groningen, 2004-2005) and the University of Cambridge (2005-2009).
In 2009 he became an ICREA Research Professor, joining the former Nanoscience and Nanotechnology Research Centre (CIN2, now the ICN2) as leader of the Oxide Nanophysics Group. In 2012 he earned an ERC Starting Grant to set up the world’s first laboratory devoted to nanoscale flexoelectricity.
