Professor Schmidt is using physical methods to investigate biological molecules. He is concentrating mainly on static and time-resolved macromolecular crystallography to investigate the structure, dynamics and kinetics of proteins. Schmidt is also developing new, sophisticated software for the analysis of the time-resolved (4-dimensional) X-ray data. Results from crystallography are corroborated by (time or energy resolved) spectroscopic methods.

Biographical Sketch

Marius Schmidt obtained his Dipl. in Biology in 1990 at Johannes-Gutenberg-University, Mainz (Germany). He received his Dr. rer. Nat. in 1996 at Technische Universität München, Garching (Germany), where later he became habilitated in Experimental Physics in 2004. In 2008 he obtained an habilitation in the French system in Theoretical, physical and analytical Chemistry.

From 1996 to 1998 Schmidt worked as a scientist for the Physics Department at Technische Universität München (Germany) and from 1998 to 2001 as a research associate for the Department of Biochemistry and Molecular Biology at the University of Chicago. From 2001 to 2007 he worked as a scientist and Privatdozent for the Physics Department at Technische Universität München (TUM), (Germany).

Schmidt has been at the University of Wisconsin-Milwaukee since 2007, where he holds the rank of Professor.
