HITS researcher Sebastian Lerch appointed ECMWF Fellow

22. April 2024

Sebastian Lerch, junior research group leader at the Karlsruhe Institute of Technology (KIT) and visiting scientist in the Computational Statistics (CST) group at HITS, has been appointed as a Fellow by the European Centre for Medium-Range Weather Forecasts (ECMWF).

The ECMWF Fellowship program fosters links between ECMWF and individual scientists carrying out pioneering work in areas relevant to ECMWF’s strategic goals.  “The overarching aim of my collaboration within the fellowship is to advance the use of methods from artificial intelligence and machine learning for improving the accuracy and reliability of probabilistic weather forecasts on subseasonal-to-seasonal timescales”, Sebastian Lerch says. Specifically, this will include the curation and development of joint datasets and testbeds to systematically evaluate and compare existing post-processing models from the groups at both ECMWF and KIT.

In the ten years since its launch, ECMWF collaborations with current and former Fellows have contributed significantly to progress in global Earth system modeling. Areas of joint work have included data assimilation, novel numerical methods, the atmospheric water cycle, predictability, and the calibration and post-processing of forecasts. One of the first ECMWF fellows was Tilmann Gneiting, CST group leader and current HITS Scientific Director.

About HITS

HITS, the Heidelberg Institute for Theoretical Studies, was established in 2010 by physicist and SAP co-founder Klaus Tschira (1940-2015) and the Klaus Tschira Foundation as a private, non-profit research institute. HITS conducts basic research in the natural, mathematical, and computer sciences. Major research directions include complex simulations across scales, making sense of data, and enabling science via computational research. Application areas range from molecular biology to astrophysics. An essential characteristic of the Institute is interdisciplinarity, implemented in numerous cross-group and cross-disciplinary projects. The base funding of HITS is provided by the Klaus Tschira Foundation.
