Background : David Ryckelynck 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 recherche). 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. It is a transfer learning approach to digital mechanics with image-based modeling of digital twins.
