** Officer of Materials Science Division from March 2020 to March 2024 

Steven De Feyter received Msc (1993) and PhD (1997) degrees from KU Leuven, Belgium, in the group of Prof. F. C. De Schryver. After a 2 years postdoc at Caltech (Prof. A. Zewail, he returned to Leuven. Since 2011, he is full professor at the Department of Chemistry (KU Leuven). From 2012 till 2016, he served as Chair of the Department of Chemistry (KU Leuven). Since 2010, he is associate editor of the RSC journal Chemical Communications. His research interests are nanochemistry and supramolecular chemistry on surfaces. Self-assembly on surfaces is a central theme of his research, with a focus on the relation between structure and function. Recent research activities cover a broad range of topics such as two-dimensional crystal engineering (e.g. formation of nanoporous surfaces, chirality at interfaces), templating, dynamics and reactivity. These studies aim at bringing insight in the fundamental aspects of molecule-substrate interactions and molecular organisation on surfaces, as well as the formation and use of these nanostructured functional surfaces (e.g. 2D materials). The liquid-solid interface is a preferred environment to induce self-assembly. Also biomolecular systems (DNA, proteins, their complexes, etc.) are investigated, with a focus on those that are involved in disease related processes. Scanning probe microscopy and spectroscopy techniques are particularly useful to probe the structural, dynamic, and electronic properties of these surface-confined molecular systems. In 2013, he was awarded an ERC Advanced Grant.
