Jahnebakken 5, 5007 Bergen, Norway

I am a Research Professor (Forsker I) at NORCE Climate. I obtained my PhD from Columbia University in 2010. After a year of postdoctoral study at the University of North Carolina, Chapel Hill I moved to Bergen, where I have resided since. I am a member of the Regional Climate and Climate Services group and I lead a research theme on Regional Climate Impacts and Modeling.

Currently my research activities flow along three interwoven and complementary strands. One is an evolution of my interests in the large scale circulation to address challenges involving prediction, representation of key features and responses of the system to external forcing. The second zooms in to local and regional scales and works to improve our understanding of physical drivers of climate impacts in places where they are most acutely experienced. The third strand aims to distill basic and applied research into useful climate information knowledge and services. This last has resulted in many fruitful collaborations with researchers and practitioners with backgrounds in Social Sciences and Humanities as well as industry and public sector professionals.

These interests result in a diverse research portfolio. I am a coordinator of the WCRP Euro-CORDEX initiative and lead projects on understanding sources of errors in our models (EMULATE) and pioneering work with so-called convection permitting models (CORDEX-FPSCONV). I also have lead roles in the Climate Futures SFI, CONFER and the Centre for Early Sapiens Behaviour (SapienCE).

Selected publications

  • Euro-CORDEX webpage
    EURO-CORDEX is the European branch of the international CORDEX initiative, which is a program sponsored by the World Climate Research Program (WRCP) to organize an internationally coordinated framework to produce improved regional climate change projections for all land regions world-wide.
  • CORDEX-FPS on Convective Phenomena over Europe and the Mediterranean
    This ground breaking initiative has established the first large multi-model ensemble of climate simulations at convection permitting scales. This allows an unprecedented view into projected changes in extreme events and their impacts.
