Research

Most of my research concerns singularities in nonlinear PDEs and the modern theory of the calculus of variations. In particular, I am interested in oscillation and concentration phenomena and what can be rigorously proved about their "shape". Applications include elasticity and elasto-plasticity theory.

On a more technical level, I work on:

  • Efficient description of oscillations and concentrations
  • Lower semicontinuity and quasiconvexity
  • Compensated compactness and, more generally, restrictions on oscillations and concentrations
  • Fine properties of functions of bounded variation/deformation
  • Rigidity and softness, convex integration
  • Rate-independent systems and plasticity

I also worked on telecommunications networks and have recently become interested in health estimation for engineering systems.

Slides from talks about several aspects of my research can be found below.
