Dirk Lehmhus earned a mechanical engineering diploma in 1998 at Volkswagen’s central laboratory, researching galvanic corrosion of magnesium alloys. The same year, he joined Fraunhofer IFAM, focusing on metallic foams, and later completed a PhD at the University of Bremen on optimizing aluminium foam production. In 2009, he became managing director of the University of Bremen’s Scientific Centre ISIS, advancing sensor-integrated materials and structures while maintaining ties with Fraunhofer IFAM. His work covered embedding sensors in cast and additively manufactured components. In 2018, he returned to Fraunhofer IFAM as a senior researcher in casting technology. He has actively contributed to international conferences such as Euromat and MS&T, and helped establish the System-Integrated Intelligence (SysInt) conference series. He serves on scientific and editorial boards and has published over 80 papers. His research focuses on light alloy casting for automotive applications, including high and low pressure die casting, compound casting, digitalization, and circular economy approaches.

He is head of the Chair of Physical Chemistry at Montanuniversität Leoben with a research focus on complex oxide materials for electro-catalytic applications. The goal is an efficient transformation of greenhouse gases (e.g. CO₂ or CH₄) into sustainable fuels and chemicals. For a fundamental understanding of catalyst structure and reactivity under real reaction conditions the emphasis is on in-situ and operando spectroscopy. Prof. Rameshan studied Chemistry at the University of Innsbruck and did his master on steam reforming of methanol on bimetallic catalysts. He conducted his PhD with a scholarship of the Fritz-Haber Institute in Berlin. For his Postdoc he went to the advanced light source in Berkeley USA to deepen his knowledge on synchrotron-based spectroscopy. At TU Wien he had a tenure track position and expanded his knowledge to the field of electrocatalysis. In autumn 2022 he was assigned full professor for electrochemical energy conversion in Leoben.
