Jan Pettersson is a Professor in the Department of Chemistry and Molecular Biology at the University of Gothenburg, where he leads research on atmospheric aerosols and their dual impact on human health and Earth's climate system. His work bridges laboratory experiments, theoretical modeling, and global field studies to address critical environmental challenges. His research focuses on: Atmospheric aerosol formation and transformation processes Cloud-aerosol interactions affecting climate Chemical analysis of airborne nanoparticles using advanced mass spectrometry Health and climate impacts of combustion and marine aerosols Field characterization of particles across diverse global environments Recent publications (2023-2025) reveal a strong emphasis on chemical speciation of atmospheric particles, particularly salt aerosols and combustion emissions. His work combines cutting-edge analytical techniques (XPS, surface ionization) with climate-relevant studies, often through international collaborations. Key themes include surface composition dynamics, alkali release mechanisms in energy systems, and planetary atmospheric processes. Professor Pettersson teaches core courses including Aerosols (KEM720) and Environmental Chemistry (KEM490), where he integrates his research on air pollution and climate science. His active publication record indicates ongoing research funding, though specific grants aren't detailed. Students benefit from opportunities in instrument development, laboratory experimentation, and field studies addressing urgent environmental questions. His research group develops specialized analytical systems for nanoparticle characterization, enabling unique insights into atmospheric processes. Current projects examine particle surface chemistry under environmentally relevant conditions, with implications for both climate modeling and air quality management worldwide.
