OpenEuroLLM - Post-Training for Large Language Models
David studied theoretical computer science at École Normale Supérieure de Lyon and holds a PhD from the University of Grenoble. He has worked at Amazon and NAVER LABS Europe.
He is currently working on LLMs4EU and OpenEuroLLM, where he leads the evaluation work package. His research focuses on machine learning, particularly in AutoML, LLMs, and predictions for tabular and time-series data. In the past, he also worked on computational topology and geometry processing.
He is very keen to contribute to open-source, he is a core developer of Syne Tune (Hyperparameter Optimization) and SlurmPilot (Python wrapper to schedule experiments on Slurm). He was also a core-developer of GluonTS (time series forecasting), Datawig (data imputation) and Gudhi (computational topology).
