Teaching & PhD Courses Sustainability ENV-101 This course presents global sustainability issues. It introduces planetary boundaries, their systemic interconnections and social justice issues. The interdisciplinary approach introduces group work and systems thinking (interdependencies in a complex system). Sustainability, climate and energy ENV-421 The course provides students with a comprehensive scientific understanding of the links between climate and energy systems in the context of sustainability. It will cover topics related to natural and anthropogenic climate change, the fundamentals of energy systems and their efficiency.

My early research was on the effect of volcanic eruptions on climate during the last 400 years. I investigated the impact of explosive eruptions, such as Tambora in 1815, in general circulation models as examples of extreme external forcing. Since then, I've been working more on the evolution of Arctic and high- to mid-latitude climates over the last 150 years. I combine in-situ, proxy, reanalysis and model data to try to untangle puzzling features and questions. I focus especially on the changing cryosphere and its impact on atmospheric circulation patterns. This includes analysing processes ranging from daily to decadal, and from regional to hemispheric resolution. Recently, I shifted my focus a little bit to seasonal prediction, combining my background of teleconnections, climate forcings and cryosphere-atmosphere feedbacks. After working for the WMO to coordinate weather and climate research projects and succesfully applying to a high-risk, high-reward Swiss National Science Foundation research grant, I am currently working as data scientist at EPFL Lausanne, combining interdisciplinary, high-frequency environmental data from the LéXPLORE platform with machine learning. Besides these scientific foci, I am highly interested in graphic and communication design. In some instances I am able to combine this interest with professional matters, such as talks, posters or figures. I often wonder about how to deliver (my) messages visually, dwelve into graphic design magazines and look out for new font types or color palettes.
