Summary
🤩
Rockstar🎓
Top SchoolDieter Werthmüller is a geophysicist and software-savvy researcher with 11+ years applying electromagnetic methods (CSEM, MT, CSAMT, GPR) to oil & gas, geothermal, groundwater and civil-engineering problems. He founded and ran an applied research consultancy in the UK, then led field and research programs in Mexico focused on CSAMT and CSEM before moving into academic and industry research roles in the Netherlands and Switzerland. At ETH Zürich he combines project management, scientific research and software development, and he has contributed practical code and documentation to major open-source projects including SimPEG and SciPy. His work bridges field geophysics, inversion software and reproducible scientific tooling—he’s a Pythonista who improves both algorithms and user-facing utilities. Fluent in cross-disciplinary collaboration, he also serves in professional societies and helped found Software Underground to support open-source geoscience. Outside work he’s an open-source enthusiast and self-described “Master Mezcalier,” a nod to a curious, hands-on temperament that complements his technical rigor.
