Rudi Hackl was member of the Gross group as a senior scientist between 2000 and 2021.

Rudi Hackl joined WMI already in 1988 as a postdoc and was since then one of the key scientists in the field of superconductivity. In particular, he became an internationally leading expert in the field of Ramen scattering. In particular, he was pioneering the application of electronic Raman scattering to the study of superconductors and correlated electron systems.

Rudi Hackl was Principal Investigator in the DFG Research Unit Doping dependence and phase transitions in copper-oxygen superconductors (FOR 538), the DFG Priority Program High-temperature superconductivity in iron pnictides (SPP1458), and the DFG Collaborative Research Center From Correlations to Functionality (TRR 80). He did his Habilitation in Physics in 1998 at the Budapest University of Technology and Economics, Hungary, and became lecturer at TUM in 2010. In 2019, he was appointed adjunct professor at TUM. Rudi Hackl retired in December 2021 after a 33 year-long succesful scientific career at WMI.
