Join our team from 01.01.2026 as Postdoc - Emerging Urban Emissions and their Impact on Atmospheric Composition At the Institute of Climate and Energy Systems - Troposphere (ICE-3) we explore the chemistry of the troposphere through atmospheric observations and simulation experiments, performs global observations, and simulates atmospheric chemistry and transport processes by numerical models.

As a postdoctoral researcher, you will join the European Research Council (ERC) Starting Grant project CHANEL – Household chemical amplifying urban aerosol pollution, led by Dr. Georgios Gkatzelis at the Institute for Climate and Energy (ICE-3), Forschungszentrum Jülich. Institute issuing the offer: ICE-3 Your Job: Urban aerosol particles pose one of the greatest global risks to human health. A substantial fraction of these particles is secondary – formed through atmospheric reactions of emitted trace gases. While motor vehicle emissions have been reduced through regulation, attention is shifting to understudied sources such as volatile chemical products (VCPs) and cooking emissions, which are now emerging as key precursors to ozone and secondary organic aerosol (SOA) in urban areas. CHANEL aims to identify the key volatile organic compounds (VOCs) that lead to SOA and ozone pollution. Using cutting-edge chemical ionization mass spectrometry, the project will perform field measurements across European cities, with a Zeppelin-based airborne platform capturing the “urban breath” of major population centers.
