Your task

Define the sensing strategy in close exchange with all collaborators
Build a dual-comb spectroscopy prototype using state-of-the-art infrastructure
Validate and benchmark the system in the laboratory using calibrated gas samples
Plan first open-path field tests and analyse the results together with collaborators.
We are looking for an ambitious postdoctoral researcher to develop dual-comb spectroscopy for atmospheric sensing and climate research. The position is hosted by the Division of Laser Physics in close collaboration with scientists from Isotope Biogeoscience, Cloud Dynamics, and Atmospheric Dynamics. The project aims to build a broadband, high-resolution optical sensing platform for isotope-resolved measurements of greenhouse gases and other trace gases, including trials towards a unique optical sensing link between Zimmerwald Observatory and the Jungfraujoch High Altitude Research Station at 3,500 metres above sea level in the Swiss Alps.

Your profile

PhD in physics, photonics, optical engineering, atmospheric physics, or a related field
Strong experimental background in ultrafast optics, laser spectroscopy, frequency-comb technology, remote sensing, or related areas
Independence, excellent project management skills and enthusiasm for interdisciplinary climate research
Additional assets: experience with dual-comb spectroscopy, nonlinear frequency conversion, free-space optical links, atmospheric sensing, or field-deployed instrumentation.

What we offer

A 2-year postdoctoral position at the interface of frequency-comb technology, laser spectroscopy, atmospheric physics, isotope science, and climate research
Access to excellent infrastructure in our laser labs and to research stations in the Swiss alps
A visible role in a new interdisciplinary initiative with strong potential for high-impact publications and follow-up funding
Attractive employment conditions and competitive salary (gross annual range CHF 91,000 – 103,000) according to the regulations of the Canton of Bern.
Diversity and inclusion
We are committed to building a diverse research group and especially welcome applications from women and people underrepresented in physical sciences. We are happy to discuss flexible working and support needs.
