Stefan Weyer

Prof. Dr. Stefan Weyer serves as a Professor in the Department of Mineralogy within the Institute of Earth System Sciences at Leibniz University Hannover's Faculty of Natural Sciences. He holds multiple leadership positions including Executive Management of the Institute of Earth System Sciences, Chair of the Audit Committee for the Geosciences Examination Board (B.Sc./M.Sc.), and membership on the Board of the Institute of Mineralogy.

Weyer's research spans multiple critical areas of geochemistry with a particular focus on isotope systems. His primary research interests include the development of Earth's early atmosphere and oceans, geochemical formation and evolution of the early solar system, magmatic evolution constrained by diffusion-driven isotope zonation in crystals, application of stable isotopes in environmental geochemistry and deposit formation, mechanisms of stable isotope fractionation of metals, and development of new analytical methods in mass spectrometry and isotope geochemistry. His work bridges fundamental geochemical processes with practical analytical advancements.

Analysis of Weyer's recent publication record reveals a strong emphasis on multi-element isotope systematics (Fe, Ni, Cu, U, Mo, Zn, Sb) applied to diverse geological settings including asteroid formation, ancient Earth environments, magmatic processes, and ore deposit formation. His research increasingly integrates advanced analytical techniques like fs-LA-MC-ICP-MS with traditional geochemical approaches, demonstrating both methodological innovation and application to fundamental Earth science questions. The publications span high-impact journals across geochemistry, planetary science, and environmental science.

Professor Weyer maintains an active research program with continuous publication output spanning over two decades, demonstrating sustained contributions to the field of isotope geochemistry. His work shows particular strength in connecting laboratory-based analytical developments with field-based geological applications across temporal scales from the early solar system to modern environmental processes.
