PhD Position in Climate Stress Impacts on the Chemistry of Forest-Derived Organic Aerosols (Forschungszentrum Jülich)

With a starting date from October 2026 we are offering PhD Position - Climate Stress Impacts on the Chemistry of Forest-Derived Organic Aerosols - Chamber and Airborne Measurements Are you excited about understanding how climate change affects forests, atmospheric chemistry and air quality? Do you enjoy experimental work, data analysis and international collaboration? As a PhD candidate you will be part of the Helmholtz Investigator Group “ClimStress - Climate stress impacts on forest emissions and aerosol pollution” led by Jun.-Prof. Dr. Eva Pfannerstill at the Institute for Climate and Energy Systems (ICE-3) within Forschungszentrum Jülich. Forests emit more than 80% of global volatile organic compounds (VOCs). These reactive trace gases drive atmospheric chemistry and are precursors to secondary organic aerosol (SOA), which affects climate through interactions with radiation and clouds. Climate change, in turn, stresses forest ecosystems and alters their VOC emissions, thereby influencing SOA formation and feeding back on climate and air quality. This PhD project aims to improve our understanding of how climate stress modifies SOA formation from biogenic VOCs, using a combination of controlled chamber experiments and airborne observations. Institute issuing the offer: ICE-3 Your Job: As a PhD candidate you will Use state-of-the-art methods to conduct gas- and aerosol-phase measurements, including the characterization and operation of an NH4+/H3O+ chemical ionization time-of-flight mass spectrometer for measuring volatile organic compounds and organic aerosol composition Investigate photooxidation processes and aerosol formation of representative biogenic VOC (BVOC) mixtures under various atmospheric conditions in the large atmospheric oxidation chamber SAPHIR Conduct airborne aerosol measurements onboard a Zeppelin airship Apply advanced data analysis methods, including statistical tools and programming, to large multidimensional datasets from chamber and airborne experiments Present your results at international conferences and publish them in peer-reviewed journals Your Profile: A Master’s degree (or equivalent) in chemistry, physics, meteorology, atmospheric sciences, environmental sciences, or related fields Strong interest in experimental atmospheric research, field campaigns and data analysis Very good experimental skills; experience in mass spectrometry and/or aerosol measurements is an advantage Experience with, or strong motivation to learn, programming (Python) and advanced data analysis methods Excellent oral and written communication skills in English Ability to communicate results clearly in presentations and in writing Self-motivated and well-structured working style Strong cooperation and teamwork skills in an international, interdisciplinary environment Our Offer: We work on pressing scientific questions that are highly relevant for society and offer you the opportunity to actively contribute to shaping change.
