Dr. Raul Arenal received his Ph.D. in Solid State Physics from U. Paris-Sud (France, 2005) and in 2013, he obtained his Habilitation (HDR) also at this University. He joined the Electron Microscopy Center in Argonne National Lab. (ANL, USA) as post doctoral fellow. In 2007, he became research scientist (ChargÃƒÂ© de Recherches) at the CNRS (France; LEM, ONERA-CNRS). From 2010 to 2011, he was visiting scientist (sabbatical position) at the Laboratorio de Microscopias Avanzadas (LMA) at the Instituto de Nanociencia de Aragon (INA) of the Universidad de Zaragoza (Spain). Since 2012, Dr. Arenal is on leave from the CNRS, and he is currently ARAID senior research scientist at the LMA-INA-U. Zaragoza. Since 2018, he is the Director of the TEM area of the LMA-INA. In 2017, Dr. Arenal has been elected member of the Young Academy of Europe (YAE) and also from this year he has been elected at the board of the YAE. Dr. Arenal is also member of the board of the Spanish Microscopy Society (SME; 2013-2021). He has published ca. 200 papers in refereed journals and edited one book (Springer) - http://www.raularenal.com . His broad area of research interest lies in electron microscopy focused on materials science and nanoscience. These studies are mainly focused on the growth mechanism, structural and physical properties of nanomaterials based on carbon, boron and nitrogen as well as other nano-structures (in particular, metallic nano-objects for plasmonic/photonic interest).
