DSc Dr Marcelo Ciappina completed his 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 and was promoted to Full Professor and granted tenure in January 2025. 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 has been 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 a 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 Physics, Nature Communications, Physical Review X, Physical Review Letters, Physical Review A). He is the author or co-author of around 200 papers in impacted journals listed in WoS. According to WoS (at Jan 2025), DSc Dr Ciappina has an h-index of 35 and his papers were cited 4304 times with a rapidly growing citation number (an average of more than 300 times during the last 5 years and more than 600 citations in 2024).
