Laboratory of Environmental Chemistry (LUC)


The Laboratory of Environmental Chemistry (LUC) focuses on fundamental research and education for assessing the impact of human activities and natural processes on human health, environment and climate. 
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. 

Michelle Worek - welcome!

A warm welcome to Michelle Worek, our new PhD student in the Laboratory of Environmental Chemistry. She will join the Analytical Chemistry group on 1 November 2022.


Welcome Giovanni Baccolo

We warmly welcome Giovanni Baccolo as Postdoc in the Laboratory of Environmental Chemistry. He joined the Analytical Chemistry group on 1 October 2022.


Jérôme Gabathuler successfully defended – congratulations!

On 26th September 2022 Jérôme Gabathuler successfully defended his PhD entitled “The thickness of the quasi-liquid layer on ice and its interaction with atmospheric gases as seen by X-ray absorption and photoelectron spectroscopies" at ETH Zürich.
