Prof. Dr. Alfred Ludwig

Prof. Dr.-Ing. Alfred Ludwig studied mechanical engineering at the University of Karlsruhe, specializing in materials science and microsystems technology. In 1999 he received the title "Dr.-Ing." from the University of Karlsruhe for his research on nanoscale magnetoelastic multilayer coatings, carried out at the Institute of Materials Research of the Forschungszentrum Karlsruhe. He then moved to the caesar research center in Bonn, in the "Smart Materials" group, where he developed high-frequency magnetoelastic coatings and devices. From December 2002 to September 2007, he was junior professor for "Werkstoffe der Mikrotechnik" at the Faculty of Mechanical Engineering of the Ruhr University Bochum (RUB) and at the same time head of the caesar research group "Combinatorial Materials Science". From October 2007 to 2012, he received a Heisenberg Professorship of the German Research Foundation for "Materials of Microtechnology" at RUB. Since the end of 2012, he has been a chair holder at RUB. From 2011 to 2016, he was coordinator of the inter-faculty "Materials Research Department" at RUB. He initiated and organized the new research building ZGH (Center for Interfacially Dominated High Performance Materials), of which he is scientific director since 2019. His research interests include high-throughput processes and MEMS tools for materials science, nanoscale layers, multifunctional materials (e.g., conventional and ferromagnetic shape memory alloys), and new materials for energy applications (e.g., materials for solar water splitting, electrocatalysts, thermoelectrics, ...). He has published more than 340 articles, more than 300 of them in peer-reviewed journals. Since 2022 he is Director of the Research Center Future Energy Materials and Systems (RC FEMS). He is PI in a new ERC Synergy Grant project (DEMI) and spokesperson of the new SFB 1625 (both projects start in 2024).
