Dr Nils P. Wedi joined ECMWF in 1995. He received his PhD degree from the Ludwig-Maximilians-Universität München. His career at ECMWF encapsulates a diverse range of work both technical and scientific. He has been a Principal Scientist since 2010 and is the Head of Earth System Modelling at ECMWF that addresses all aspects of scientific and computational performance relating to ECMWF's forecast model and the ensemble forecasting system. He develops strategies to secure the scalability of the model on future high-performance computing systems. He is the scientific coordinator of the European H2020 project ESCAPE to address the challenges of rising energy cost for computing towards affordable, exascale high performance simulations of weather and climate, and he is a member of the WMO working group on numerical experimentation (WGNE).






Professional interests: 

Nils' interest is in numerical weather prediction and a widening perspective on relevant Earth system components such as atmosphere land interactions, oceans, waves, and sea-ice, with a broad expertise in numerical methods, atmospheric dynamics and physics, across scales from global to laboratory.
