Leif Denby is Senior Research Scientist at the Danish Meteorological Institute (DMI) and Visiting Research Fellow at the University of Leeds. He holds a PhD in Atmospheric Physics from the University of Cambridge. Since joining DMI in 2023 he has formed the DMI SciML community and co-created the mllam and mlcast open-source communities for data-driven weather forecasting and nowcasting, and led the DMI team that built the first Graph Neural Network weather forecasting model trained on 30 years of DANRA 2.5km reanalysis data using the Gefion supercomputer. At Digital Tech Summit, Leif will have a presentation on "Faster, Learned Forecasts: ML Weather Prediction in Practice at DMI".
