Felix Luond is a researcher at the Swiss Federal Institute of Metrology, METAS. He obtained his PhD in atmospheric ice nucleation for which he was awarded the ETH medal. His experimental work focused on cloud microphysics. He specialized in the development of dedicated instrumentation to study aerosol-induced freezing of cloud droplets and the interpretation of resulting experimental data in the framework of nucleation theory and its advancements. Currently, Dr Luond's research activities concentrate on aerosol metrology, particularly in the generation of ambient-like aerosols dedicated to est...
