Avak Sven Defense.JPG

Congratulations to Sven Avak

On 31 January 2019 Sven successfully defended his PhD entitled “Impact and Implications of Melting on the Preservation of Trace Elements in High-Alpine Snow and Glacier Ice" at the University of Bern. Congratulations! This thesis formed part of the collaborative project Microscale Distribution of Impurities in Snow and Glacier Ice (MiSo) in co-operation with LUC's Surface Chemistry research group and the WSL-SLF Davos. The project was funded by the Swiss National Science Foundation.

Welcome Martina Barandun

We warmly welcome Martina Barandun as Postdoc in the Laboratory of Environmental Chemistry. She joined the Analytical Chemistry group on 1 October 2018.

Martina Barandun studied Geography at the University of Fribourg, where she also obtained her PhD in the Department of Geosciences. For the latter she worked on transient snowline observations to remotely derive seasonal to sub-seasonal glacier mass balance in the Tien Shan and Pamir mountains of Central Asia. At PSI, Martina Barandun will quantify the concentration of different light absorbing impurities such as black carbon or mineral dust particles in surface snow and ice from various glaciers in Central Chile, to estimate their impact on albedo reduction and accelerated melt. This is a joint project with the Centro de Estudios Cientificos in Valdivia, Chile.

Congratulations to Pablo Corral Arroyo

Pablo successfully defended his PhD at the University of Bern, entitled "Impact of indirect photochemistry of Brown Carbon and iron carboxylate complexes on gas and aerosol chemistry". This thesis formed part of collaborative project with ETH Zürich on the feedbacks between microphysics and photochemistry in organic aerosols funded by the Swiss National Science Foundation.

Welcome Jérôme Gabathuler

Join me in welcoming Jérôme, our new PhD-student in Markus Ammann's group.

He got his master in applied physics at the EPF Lausanne. During his master thesis, he worked on "Solar water purification using photocatalysis with a novel TiO2 nano-porous aerogel“. At PSI, Jérôme Gabathuler will be studying the surface of ice samples using X-ray excited electron spectroscopy at the Near Ambient Pressure Photoemission (NAPP) endstation at SLS. His thesis work is part of the SNF funded project entitled "Interfacial Chemistry of Ice: Photolysis and Acid-Base Equilibria in the QLL and Brine“.

LUC Excursion Sargans.JPG

LUC goes underground

During this year's excursion we experienced the underground world on a guided tour through the Gonzen iron mine in Sargans. While walking up and down the impressive system of galleries and tunnels the extreme working conditions of the miners became palpable. After the 3.5 hours underground we happily returned to our labs at PSI.
