Arrigo Calzolari received his PhD in Physics at the University of Modena and Reggio Emilia in 2003. He has been a researcher at the Institute of Nanoscience (CNR-NANO) in Modena since 2010, and a member of the AFLOW consortium for material Materials Genomics since 2015. He is a faculty member of the PhD school of Physics and Nanoscience at the University of Modena and Reggio Emilia (2018-present), a member of the scientific panel of the PRACE-ICEI EU initiative (since 2020), and a member of the European Materials Modelling Council—EMMC ASBL (since 2021). Previously, he operated as a researcher at the CNR-IOM Institute (Trieste, IT, 2009-2010), an external collaborator at SISSA (Trieste IT, 2013-2015), and an adjunct research professor at the Physics Dept., University of North Texas (2012-2014). He coordinates the research group “ab initio materials simulations for optoelectronics and energy-AMUSE”, which operates in the field of condensed-matter and solid-state physics, performing first-principle simulations at the DFT level and beyond. His research activity is focused on computational material science, mostly based on ab initio studies within the Density Functional Theory (DFT) framework and beyond (TDDFT, DFPT) of the structural, electronic, optical, vibrational, plasmonic, and transport properties of materials, nanostructures, molecules, and interfaces, for energy conversion, electronics, and nanotechnology applications.
