ultibody systems applications
multilevel methods
numerical methods for differential equations with constraints
scientific computing


The focus of my work is on the investigation and promotion of novel, efficient and reliable methods in scientific computation, particularly for approximation and optimization problems involving differential equations with constraints.

Thus, in addition to generally investigating properties of numerical methods I have been involved also in writing general-purpose mathematical software; investigating parallel algorithms and optimization techniques; solving inverse problems involving differential equations; and getting more specifically involved in particular application areas such as multibody systems simulation, robotics, data inversion in geophysics, 3D electromagnetic modeling, image reconstruction, cloth simulation and computational fluid dynamics.
