Professor Arnulf JENTZEN is a Professor at The Chinese University of Hong Kong, Shenzhen. In addition, since 2019 he has been employed as a Professor for Applied Mathematics at the Faculty of Mathematics and Computer Science in the University of Münster. He received his Diploma (2007) and PhD (2009) in Mathematics from Goethe University Frankfurt.
The core research topics of Professor Arnulf Jentzen are machine learning approximation algorithms, computational stochastics, numerical analysis for high dimensional partial differential equations (PDEs), stochastic analysis, and computational finance. He is particularly interested in deep learning based algorithms for high dimensional approximation problems and different kinds of differential equations.
Professor Arnulf Jentzen has received a number of awards for his research contributions. In particular, he is the winner of the 2018 Joseph F. Traub Information-Based Complexity Young Researcher Award and in 2020 he has been awarded the Felix Klein Prize of the European Mathematical Society (EMS). He has also successfully obtained several research grants for his research activities. Professor Arnulf Jentzen has been invited to work as editor of many international top magazines, such as the Annals of Applied Probability (AAP), Communications in Computational Physics (CiCP), Communications in Mathematical Sciences (CMS), the Journal of Complexity (JoC), the Journal of Mathematical Analysis and Applications (JMAA), the SIAM/ASA Journal on Uncertainty Quantification (JUQ), the SIAM Journal of Scientific Computing (SISC), and the SIAM Journal on Numerical Analysis (SINUM). Since he has received his PhD in October 2009, he has been invited to more than 100 research talks and 5 minicourses. In addition, he has collaboratively organized a series of workshops, minisymposia, and programmes, respectively.
