About Fredrik Hellman
My research focuses on multi-scale methods for solving partial differential equations (PDEs) with rapidly varying coefficients. In particular, I study methods where different but similar coefficients appear in a set of problems, for example in stochastic simulation of defect materials or time-dependent PDEs.
