Plenary lecture at 7th GACM Colloquium on Computational Mechanics in Stuttgart 2017. Invited lecture at Centrale Supélec 2016. **Background** : David Ryckelynck is working on model-based/physics-based engineering assisted by machine learning. He did seminal works on hyper-reduction methods, also termed hyperreduction, in the field of applied mathematics and computational mechanics. This method couples machine learning and projection-based model order reduction. Without counting for self citations, hyper-reduction has been cited 544 times in peer reviewed papers, according to Web of Science in 2019. Hyper-reduction methods can be seen as an extension of non supervised machine learning for dimension reduction to the field of model order reduction for the approximate solution of partial differential equations. He also did seminal works on “a priori model reduction” with 227 citations in peer reviewed paper without counting self citations in 2019. He has been the supervisor of more than 25 PhD theses in computational mechanics. He has supervised Nissrine Hakkari and Fabien Casenave for their degree of Doctor of Science (Habilitation à diriger des recherches). He was the head of a research team involving 12 permanent researchers at Mines ParisTech, from 2011 to 2015. He is the head of a new lecture on Ingenierie Digitale Des Systemes Complexes (Data Science for Computational Engineering) at Mines Paris PSL University. This lecture has been created by Pr. David Ryckelynck and Pr. Elie Hachem in 2017. In this lecture, a team of 10 lecturers are teaching to students of Mines Paris the way that simulation data and experimental data can be used in machine learning. We focus our attention to hybrid approaches that combines machine learning and usual modeling methods in engineering. His main topic of research is now image-based digital twins via machine learning, including dimensionality reduction for both images and simulation data. He is developping new data augmentation methods for engineering applications. **Awards** Prix de thèse Maths Entreprises 2022 for Thomas Daniel (PhD 24th september 2019 Mines Paris PSL University) from Agence Maths Entreprises (AMIES), France. **Best papers** A priori hyperreduction method: an adaptive approach, Ryckelynck, D, JOURNAL OF COMPUTATIONAL PHYSICS Volume: 202 Issue: 1 Pages: 346-366 Published: JAN 1 (2005).
