Dr. CESAR MAGEN. PhD in Physics in 2005 at the University of Zaragoza in the field of magnetocaloric materials. In 2006 he began his activities in the field of advanced aberration corrected TEM techniques, firstly as a postdoctoral fellow at the CEMES-CNRS (Toulouse, France, 2006-2007), later in the Oak Ridge National Laboratory (Tennessee, USA, 2007-2008). In 2008 he was awarded an ARAID Fellowship to continue his research activities at the Instituto de Nanociencia de Aragón (INA) of the University of Zaragoza. He has been scientific staff of the Laboratorio de Microscopías Avanzadas (LMA) since its foundation, supervising the installation and setup of the first aberration corrected TEMs in Spain (2009) and Coordinator of the TEM Area of the LMA node of the ICTS-ELECMI in 2016-2017. Since 2014 he is Associated Professor of the University of Zaragoza. In June 2017 he is appointed Staff Researcher of the Spanish Research Council (CSIC) at the Instituto de Ciencia de Materiales de Aragón (ICMA). His current research interests focus on the development of novel functional nanomaterials in the fields of the complex multiferroic oxides and Nanomagnetism by the application of different advanced TEM techniques, such as aberration corrected STEM imaging and spectroscopy, and off-axis electron holography. Dr. Magén has co-authored about 170 publications in international peer reviewed journals, with an h-index of 30. He has given more than 30 invited talks in national and international conferences as well as participated in numerous workshops and schools on electron microscopy.
