Biosketch

After my PhD in UAB I worked for two years in Universitat de les Illes Balears as Associate Professor (2000-2001). In 2009 I had the award “I3 Intensification young researchers DIUE-MEC 2007 (2009-2011)”. I have the “Acreditation of Advanced Research Position” by AQU-Catalunya and the "Full Professor Acreditation" by ANECA". Coordinator of the Spanish Dynamical Systems Network from 2018. PI of some Spanish research projects from 2014.
