The effect of human activities on climate and the environment is a grand challenge facing society today.
Our lab studies atmospheric processes and their impacts on climate, health and ecosystems through a combination of theory, measurement and modelling. A central focus in our research program is atmospheric particulate matter (aerosols), and studies often combine observations, theory and modelling. We are involved in the development of aerosol instrumentation, and measurement techniques required to study processes and constrain parameters for models. Our group develops open-source modules routinely used in air quality and climate models, as well as tools for advanced sensitivity analysis of large codes and model reduction/data discovery through emulation and network analysis. We are also heavily involved in field measurement programs on understanding the climate and health impacts of ambient aerosol.
LAPI is very closely affiliated with the Center of Studies on Air quality and Climate Change (C-STACC) of the Institute of Chemical Engineering of the Foundation for Research and Technology Hellas at Patras (Greece) and the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology (US), where the LAPI director maintains affiliations and active research groups and lab facilities. LAPI also maintains a large number of active collaborations with leading groups worldwide.

EPFL launched a pioneering project to detect pollen, dust and smoke
Since the start of this year, a suite of instruments has been hard at work detecting a broad spectrum of aerosols at the MeteoSwiss weather station in Payerne, in Vaud Canton. This pioneering project – a joint initiative between EPFL, the Swiss Federal Office of Meteorology Climatology and European partners – aims to improve pollen forecasting and to gain further insights into the critical impact that bioaerosols, smoke and dust have on cloud formation and climate.
Acids help against airborne viruses
A new study by various Swiss universities, including EPFL, shows that aerosols in indoor air can vary in acidity. This acidity determines how long viruses such as influenza and SARS-CoV-2 remain infectious in the air – with profound implications for virus transmission and strategies to contain it.
