PhD student Snow Water Equivalent innovative sensor development; f​/m​/d

You will work on a research project funded by the Swiss National Competence Center Muoniverse. Muoniverse is dedicated to advancing muon science across particle physics, quantum materials, and applications ranging from energy research to cultural heritage.

You will be collaborating with the Paul Scherrer Institute (PSI) to validate and deploy their DMAPS muon sensors for measuring Snow Water Equivalent (SWE) in alpine environments. Your work will begin at the Weissfluhjoch test site, where you will cross‑validate sensor readings with existing automated and manual snow measurements (e.g., snow scale, snow profiles, SMP). You will also conduct high‑frequency manual sampling during key events to capture temporal dynamics.

Once validated, you will deploy multiple sensors to study small‑scale SWE variability during mass redistribution and loss events, and later in heterogeneous terrain like ridges, generating unique datasets to advance our understanding of snowpack dynamics.

• Collaborate with PSI to validate and deploy DMAPS muon sensors.
• Cross‑validate sensor readings with existing automated and manual snow measurements.
• Conduct high‑frequency manual sampling during key events.
• Deploy multiple sensors to study small‑scale SWE variability during mass redistribution and loss events.
• Study SWE variability in heterogeneous terrain such as ridges.

• Master’s degree in science or engineering.
• Background in experimental work, data analysis, and field measurements.
• Solid knowledge of a high‑level programming language such as Python.
• Ability to handle large data sets.
• Experience with snow hydrology, cryosphere monitoring, or particle physics instrumentation is a plus.
• Independence, problem‑solving skills, and ability to work in alpine conditions—including during winter field campaigns.
• Fluency in English (written and spoken) required; knowledge of German beneficial.
