Postdoctoral Fellows in Aerosol Chemistry Paul Scherrer Institute (PSI) in Switzerland

The Paul Scherrer Institute (PSI), Switzerland's largest research institute for natural and engineering sciences, is seeking two Postdoctoral Fellows in aerosol chemistry for its Laboratory of Atmospheric Chemistry. PSI is renowned for its interdisciplinary research in future technologies, energy and climate, health innovation, and the fundamentals of nature, with a strong commitment to training future generations of scientists. The institute employs over 2300 staff, including a significant proportion of post-docs and post-graduates, fostering a dynamic and collaborative environment.

The successful candidates will engage in mass spectrometry measurements using aerosol mass spectrometers and extractive electrospray ionization mass spectrometry. Research will focus on the health relevance of aerosols, utilizing oxidative potential as a marker for health impact. Statistical source apportionment analysis and participation in measurement campaigns, including fieldwork in Romania, are integral components of the role. Fellows will also support other postdoctoral researchers and PhD students in various campaigns and contribute to impactful scientific publications.

Applicants must possess a PhD degree in atmospheric science, demonstrate proficiency in aerosol mass spectrometry, and have substantial experience in data analysis and programming (preferably Python). A strong publication record and excellent English communication skills are required, alongside a team-oriented working style.

PSI offers an initial two-year employment contract with the possibility of extension, modern employment conditions, and comprehensive on-site infrastructure.
