About Klas Modin

Klas Modin is a researcher within geometric mechanics and geometric numerical integration. In these field, differential geometric methods are used to study continuous dynamical systems and to develop structure preserving numerical integration algorithms. Of particular interest are Euler-Arnold equations, describing geodesic motion on Lie groups. Many differential equations in physics fall into this category, for example Euler's fluid equations for the motion of an inviscid incompressible fluid. Klas is working with a novel application of Euler-Arnold equations to medical image registration, for which he recieved an "Ingvar Carlsson Award" from SSF in 2013.
