Benjamin Tobias Brem

Dr. Benjamin Tobias Brem is a Scientist at the Paul Scherrer Institute (PSI) in Switzerland, affiliated with the Center for Energy and Environmental Sciences and the Laboratory of Atmospheric Chemistry. His research focuses on aerosol chemical, microphysical, and optical properties, particularly through long-term observations at the high-alpine Jungfraujoch research station within the Global Atmosphere Watch (GAW) and Aerosol, Clouds and Trace Gases Research Infrastructure (ACTRIS) frameworks.

• Specializes in aviation emissions and air quality impacts in the APPROPRIATE project
• Contributes to aerosol-cloud-precipitation interaction studies
• Develops calibration methods for aerosol monitoring instruments
• Advances understanding of ice-nucleating particles and ultrafine particle sources

His work spans atmospheric chemistry, environmental engineering, and climate science. Recent publications analyze sustainable aviation fuels, Saharan dust transport, and aerosol health effects. He participates in the Swiss Commission for Atmospheric Chemistry and Physics (ACP) under SCNAT.
