David is an analytical scientist born in Paderborn, Germany. He completed his B.Sc. (2012), M.Sc. (2014), and PhD (2017) in º£½ÇÉçÇø at the University of Münster under Professor Uwe Karst. After his doctorate, he received a DFG Fellowship and joined Professor Philip Doble’s group at the University of Technology Sydney, later becoming a lecturer in chemistry. In 2021, he returned to Europe to take up a tenure-track position at the University of Graz, Austria, where he founded and now leads the NanoMicroLab. Promoted to Associate Professor in 2024, he currently heads a team of eight researchers.

David is passionate about atomic spectroscopy, particularly ICP-MS in its many facets, ranging from fundamental principles and instrumentation to hyphenation with complementary techniques and real-world applications. His early work focused on LC-ICP-MS and LA-ICP-MS, while his current research centres on ICP-TOFMS and single particle approaches. His group develops new hyphenated techniques combining ICP-MS with orthogonal technologies such as optical traps and Raman spectroscopy to gain deeper insights into complex particulate systems.

With about sixty scientific articles published, his work has received broad recognition, including an ERC Starting Grant, the GDCh Analytical º£½ÇÉçÇø Division Award, the ASAC Fritz Feigl Award, and the DGMS Mattauch-Herzog Award. He serves on the advisory boards of four journals and remains active as a reviewer, guest editor, and scientific committee member. His research has been featured at numerous international conferences through keynote and invited lectures, as well as short courses
