PhD Position – Climate Stress Impacts on the Chemistry of Forest-Derived Organic Aerosols – Chamber and Airborne Measurements Full-time

PhD Candidate Position

As a PhD candidate you will:

1. 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
2. Investigate photooxidation processes and aerosol formation of representative biogenic VOC (BVOC) mixtures under various atmospheric conditions in the large atmospheric oxidation chamber SAPHIR
3. Conduct airborne aerosol measurements onboard a Zeppelin airship
4. Apply advanced data analysis methods, including statistical tools and programming, to large multidimensional datasets from chamber and airborne experiments
5. 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:

• Team & environment: A dynamic, international and motivated team at one of the largest research institutions in Europe
• Research & infrastructure: Access to excellent scientific and technical facilities, including state-of-the-art atmospheric simulation chambers (e.g. SAPHIR) and advanced instrumentation
• Networking & exchange: Participation in (international) conferences, enabling you to build and expand your scientific network
• Personal development: Opportunity to join the HITEC graduate school, offering additional scientific and professional training, as well as options for international research stays
• Support for international employees: Our International Advisory Service supports you with all questions related to starting work and living in Germany
• Work-life balance: 30 days annual leave and flexible working arrangements (including remote work) are generally possible by agreement and in line with tasks and on-site requirements
