The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting‑edge research in the fields of future technologies, energy and climate, health innovation and fundamentals of nature. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations, with about one quarter of our staff being post‑docs, post‑graduates or apprentices. PSI employs 2,300 people.
Project Overview Your project will focus on the non‑CO2 emissions from aircraft engines, both from large aircraft and smaller unregulated engines.
Position Postdoctoral Fellow in Atmospheric Science
(Laboratory of Atmospheric Chemistry)
Responsibilities
Lead and organise campaigns at an aircraft test bench and at a commercial airport.
Characterise, operate and calibrate an online mass spectrometer equipped with an extractive electrospray ionisation mass spectrometer to measure inorganic and organic components of the aerosol and quantify oil emissions.
Characterise the volatile components of aircraft exhaust emissions with a proton‑transfer‑reaction mass spectrometer.
Understand the formation potential of secondary organic aerosol and its composition using an extractive electrospray mass spectrometer and an oxidative flow reactor.
Maintain an aerosol mass spectrometer and be responsible for aerosol instrumentation during campaigns to measure aircraft emissions.
Collaborate with various partners, including international collaborators.
Profile
PhD degree in Physical Chemistry, Chemistry, Environmental Sciences or a related field.
Ability to produce data under supervision and capable of critical analysis, evaluation and synthesis of new and complex ideas.
Familiarity with mass spectrometry and atmospheric chemistry.
Ability to communicate the outcomes of your research.
Good interpersonal skills and a team player.
Good knowledge of English (written and spoken).
Benefits Your employment contract is limited to 2 years, with the possibility of extension depending on project development and funding. You will receive systematic training on the job, personal development opportunities, a supportive work‑life balance and modern employment conditions, including on‑site infrastructure.
