Research Interests

I generally work in the field of Calculus of Variations and Partial Differential Equations. My current work focuses on variational models for problems from materials science, like fracture mechanics, dislocations and mixtures of fluids. Further I have a general interest for more abstract Calculus of Variations and PDE theory.
