In 2004 he started his undergraduate studies in mathematics at Goethe University Frankfurt in Germany, in 2007 he received his diploma degree at this university, and in 2009 he completed his PhD in mathematics at this university. The core research topics of his research group are machine learning approximation algorithms, computational stochastics, numerical analysis for high dimensional partial differential equations (PDEs), stochastic analysis, and computational finance. Currently, he serves in the editorial boards of several scientific journals such as the Annals of Applied Probability, the Journal of Machine Learning, the SIAM Journal on Scientific Computing, the SIAM Journal on Numerical Analysis, and the SIAM/ASA Journal on Uncertainty Quantification. His research activities have been recognized through several major awards such as the Felix Klein Prize of the European Mathematical Society (EMS) (2020), an ERC Consolidator Grant from the European Research Council (ERC) (2022), the Joseph F. Traub Prize for Achievement in Information-Based Complexity (2022), and a Frontier of Science Award in Mathematics (jointly with Jiequn Han and Weinan E) by the International Congress of Basic Science (ICBS) (2024).
