Laboratory of Environmental Chemistry
The surface chemistry research group investigates multi-phase chemical processes relevant for atmospheric chemistry and the analytical chemistry research group reconstructs environmental and climatic conditions from high-altitude glaciers.
The Latest News
Welcome to Lucia Iezzi
We warmly welcome Lucia Iezzi as a PhD student in the Laboratory of Environmental Chemistry. She has joined the Surface Chemistry group on 1 November 2020.
Welcome to Fabian Mahrt
We gladly announce that Fabian Mahrt has started to work as Postdoc in the Laboratory of Environmental Chemistry. He formally joined the Surface Chemistry group on 1 August 2020 but has started his work actually at the University of British Columbia (UBC), Canada.
Congratulations to Ling Fang
On 2 June 2020 Ling successfully defended her PhD entitled “Radiocarbon analysis of dissolved organic carbon from ice cores" at the University of Bern. This was the first time that a student from our lab defended online and Ling delivered a great performance. Congratulations! The project was conducted in collaboration with the Laboratory for the Analysis of Radiocarbon with AMS (LARA) of the University of Bern, Nanjing University, and the University of Maine, amongst others, and funded jointly by the University of Bern and the Paul Scherrer Institute.
Current Scientific Highlight
The glacial memory of the Monte Rosa
The next mission to preserve the climate heritage of the Pennine Alps has begun: For the Ice Memory Project, researchers set off for Monte Rosa’s Colle Gnifetti.
Particulates are more dangerous than previously thought
A precise look into the finest particles in the air shows how compounds harmful to human health are formed.
"We were shocked how far advanced the melting is already"
An international expedition with the participation of the Paul Scherrer Institute PSI discovers advanced glacial melting at an elevation of more than 4,000 metres on the Grand Combin in Valais. In the Alps, it may almost be too late for the Ice Memory project, which aims to save ice cores as a climate archive for future generations of researchers.
