Barbara A. J. Lechner

Short CV

Barbara A. J. Lechner studied Chemistry at the University of Innsbruck, Austria. She obtained her Ph.D. in Physics from the University of Cambridge in 2012. As a postdoctoral fellow, she joined the group of Prof. Miquel Salmeron at the Lawrence Berkeley National Laboratory, CA, and subsequently became a group leader at the Chair of Physical Chemistry at TUM. She received an ERC Starting Grant in 2019. Since May 2018, she is a member of the “Young Academy” of the Bavarian Academy of Sciences. In October 2020, she was appointed Rudolf Mößbauer Tenure Track Professor at the Department of Chemistry of TUM.

Research Interests

Barbara Lechner’s research focusses on the investigation of the dynamic restructuring of functional nanomaterials under realistic conditions, e.g. model catalysts under a reactive gas atmosphere. To this purpose, they place a scanning tunneling microscope with high temporal and spatial resolution directly into gas mixtures and thus investigate how the structure of particles (metal clusters) and oxide supports changes under these conditions. By using small clusters with a precisely defined number of atoms, it is possible to investigate how the formation and decay of highly reactive particle structures occurs, can be controlled and how such structural changes influence the function of a material.
