DSc Dr Marcelo Ciappina completed the PhD in Physics at Balseiro Institute, Argentina, in March 2005 and the Research Professor in Physico-Mathematical Sciences (DSc) dissertation (Habilitation) at the Czech Academy of Sciences, Czech Republic in June 2019. After several years of Postdoctoral and Senior positions all around the world, including, amongst others, various Max Planck Institutes in Germany (MPI-K Heidelberg, MPQ Garching and MPI-PKS Dresden), the Institute of Photonic Sciences (ICFO) in Spain, the Extreme Light Infrastructure (ELI)-Beamlines in Czech Republic, the Institute of High Performance Computing (IHPC) (A* STAR, Singapore) and the Auburn University (USA), he joined the GTIIT in fall 2020 as an Associate Professor. DSc Dr Marcelo Ciappina is a top-class expert in theory and numerical simulations of nonlinear laser interactions with atoms, molecules and complex systems. The most important effects during these interactions are high-harmonic generation (HHG), the generation and application of attosecond extreme ultraviolet (XUV) pulses, above-threshold ionization (ATI) and non-sequential ionization (NSI).  In a few recent years he is one of the pioneers in a novel and fascinating field that merges two relatively new areas of research: attosecond and nanoscale physics. This research area particularly studies how nanometer-spatially inhomogeneous laser induced fields modify the laser-driven electron dynamics. Consequently, this field property has profound impact on pivotal processes such as ATI and HHG. DSc Dr Ciappina is developing analytical and numerical methods for the description of the above physical processes and he is carrying out numerical simulations supporting different strong laser-matter experiments worldwide. He participates in the interpretation of experimental results and also in the proposals for new experiments. DSc Dr Ciappina regularly publishes in very prestigious scientific journals (Nature Communications, Physical Review X, Physical Review Letters, Physical Review A). He is author or co-author of more than 130 papers in impacted journals listed in WoS. He is the first author of a authoritative review paper Attosecond Physics at the nanoscale published in Report on Progress in Physics (IF 14.311) in 2017. According to WoS (at Oct 2020), DSc Dr Ciappina has an h-index 24 and his papers were cited 2110 times with rapidly growing citation number (an average of around 300 times during the last 3 years).
