Research Profile

A main focus of current research is the approximation of high-dimensional functions and the solution of partial differential equations in high dimensions. Our central tool in this respect is the dimension-adaptive sparse grid method and its generalizations. Another focus is the development of efficient numerical methods for the treatment of two-phase-flow problems and for the simulation of materials on the atomistic and the continuous scale with special emphasis on nano-technology. Finally, adaptive discretizations for partial differential equations, multi-level solvers of the arising linear systems and their parallelization have been investigated.

A main focus of future research will be numerical data analysis. This involves high dimensional regression, density estimation and classification problems in high-dimensional spaces. The emphasis will be on the development of new numerical techniques and on proposing stable algorithms as well as on establishing theoretical results. The research will be driven by real data applications in econometrics and finance and by data-oriented problems from material science. Since data often stem from a low-dimensional manifold embedded in ambient space, we aim at exploiting this structure by applying adaptive sparse grid algorithms for the h-version, the p-version and the kernel-based versions of approximation. Moreover, we will develop nonlinear methods beyond the Hilbert space setting. To this end, we will replace the conventional Euclidean cost function by more appropriate distance measures such as Banach space norms or Bregman divergences. Here, we again aim at deriving both, a theoretical foundation and stability conditions with error estimates for practical purposes. Finally, we plan to study the relation of our nonlinear methods to deep neural networks.
