Research interests:   

My research is focused on the mathematical description of highly deformable materials, structures and systems with a particular interest in:

Soft Robotics and flexible multibody dynamics

  • Dynamics and control of soft robots using finite element formulations
  • Development of tailor-made simulation environments for flexible multibody systems
  • Contact mechanics within the field of nonsmooth dynamics

Mechanical metamaterials and computational mechanics

  • Development of novel mathematical theories for micro-structured materials
  • Design, modeling and analysis of materials with second-gradient elasticity effects
  • Variational formulations and numerical treatment of spatial nonlinear beam theories
