I am a climate scientist with interest in extreme weather events.
I have been at CICERO since June 2016 and currently work on three projects: TWEX, S2S4E and EXHAUSTION. I use the output of a wide range of models - global climate models, regional models, weather forecast models, seasonal forecast models and hydrological models - to extract information about extreme events relevant for users. I also serve as an associate editor for the journal Atmospheric Science Letters.
I obtained an early career mobility fellowship from the Swiss National Science Foundation in 2013 and joined the Environmental Change Institute, University of Oxford, to work on probabilistic event attribution. A year later, I moved to the Department of Physics, University of Oxford, as a postdoc on the EUCLEIA project. I combined attribution studies with seasonal forecasting techniques to develop new methodology for representing the level of confidence in attribution results so that attribution products can be trusted to inform decision making. During my time in Oxford, I was a Junior Research Fellow at Wolfson College.
During my PhD (2009-2012) at ETH Zurich, Switzerland, my research focused on methods to evaluate global climate models for precipitation and quantifying the response of the Earth's hydrological cycle and energy cycle in future warming scenarios. One of my interests lies in investigating whether the climate system responds linearly to carbon dioxide forcings of different intensities. I have also been involved in studies about the reversibility of the climate system's state and in particular how changes in the ocean circulation can affect the surface climate.
I hold a BSc in Earth Sciences and a MSc in atmospheric and climate science with a Minor in physical glaciology, both from ETH Zurich.
- Translating Weather Extremes into the Future – a case for Norway TWEX-Future.no will be taking a novel “Tales of future weather” approach. This approach suggests that scenarios tailored to a specific region and stakeholder in combination with numerical weather prediction models will offer a more realistic picture of what future weather might look like, hence facilitating adaptation planning and implementation.
- ClimateXL Weather and climate extremes are likely to be one of the largest societal challenges associated with climate change in this century. Under climate change, these extreme events will intensify and become more frequent, and consequently the risk of severe and costly damage for humans and infrastructure will increase.
- S2S4E Climate Services for Clean Energy S2S4E is a European climate services innovation project funded by Horizon2020. CICERO is the second largest partner of the consortium and leads two work packages.
- Exhaustion Air pollution is currently the largest environmental killer in Europe, causing 500,000 premature deaths annually. Heatwaves can make air pollution more lethal and cause more heart and lung diseases. Together with Universitetet i Oslo (UiO) the Norwegian Institute of Public Health and 11 other European institutions CICERO will help increase European resilience towards climate change.
