My research focusses on the development and application of Lagrangian atmospheric transport models, with a further specialisation on flow in mountainous terrain and inverse modelling of greenhouse gas fluxes.

These models can be applied to study various atmospheric trace compounds and their atmospheric budgets. Specifically, I work on the estimation of regional non-CO2 greenhouse gas fluxes ranging from the well know 'big' players methane and nitrous oxide, to synthetic gases (e.g., hyrdofluorocarbons, HFCs) that are only present a very low concentrations in the atmosphere, but yet may have a large impact on climate change.

Trace gas transport in the near-surface atmosphere becomes progressively challenging in mountainous areas, like those of the Swiss Alps. We do our simulations at multiple atmospheric scale to address this challenge, ranging from kilometre-scale to global transport.
