Experience

  • Researcher at Empa
    Apr 2025 - Present · 1 yr 3 mos

    I oversee the design, installation, and maintenance of an advanced laser spectroscopy system and the improvement and maintenance of a core spectrometer at the Jungfraujoch Research Station—both designed to continuously measure isotopic variations in atmospheric carbon dioxide. By collaborating with interdisciplinary teams on these projects, I provide precise and long-term atmospheric data to deepen our understanding of atmospheric processes and support the global transition to a climate-neutral society.

  • University of Basel (Full-time · 6 yrs 3 mos)
    • Postdoctoral Researcher
      May 2024 - Mar 2025 · 11 mos

    • Doctoral Student
      Jan 2019 - Apr 2024 · 5 yrs 4 mos

      I am responsible for the operation and management of a cryogenic scanning setup for quantum sensing applications. My duties include the handling of state-of-the-art optical setups, microwave circuits, and different cryogenic systems. Additionally, I am involved in the nanofabrication of diamond-based scanning probes and the development of novel measurement schemes and analysis protocols in the field of single-spin quantum sensing. My research projects are focused on studying the exotic class of two-dimensional magnets, contributing to the advancement of knowledge in this emerging field.

  • Master Thesis at Fraunhofer IPM
