Dr. Gilbert Grell

Gilbert Grell obtained his Master's degree (2015) and PhD in theoretical Physics (2020) at the University of Rostock, Germany. This work was focused on the development of methods for the simulation of photoionization and Auger-Meitner decay in organic molecules and transition metal complexes.

These methods have been facilitated to model X-Ray spectroscopic observables, allowing for the interpretation of experimental measurements in terms of the molecular electronic structure.
He moved to IMDEA nanociencia for a postdoctoral stay with Fernando Martín in March 2020, changing gears to the development of methods for the ab-initio simulation of ultrafast molecular dynamics induced by broad-band attosecond to few femtosecond laser pulses. Such pulses create a coherent superposition of electronic states, giving rise to electronic motion on the attosecond to few-femtosecond timescale.

Understanding this dynamics is prerequisite to its eventual control, the ultimate goal of the emerging field of attochemistry. A large part of his postdoctoral work has therefore been devoted to the development of ab-initio simulation approaches for time-resolved spectroscopies, in which an attosecond or few femtosecond pump pulse creates a coherent superposition of electronic states, the evolution of which is then interrogated with a delayed, similarly-short probe pulse, unraveling the coherent electronic motion.
