Research area
My research is focused on computational methods in dynamics of multibody systems with contact and friction. This comprises all aspects, from geometric representation and contact detection, through kinematic models and time integration, to formulation and solution of the frictional contact problem. I work on High Performance Computing implementation of implicit multibody time stepping methods. Solfec is currently the main software output of my work.
