My research focuses on the
  • development and
  • numerical analysis
of finite element methods in complex applications, including
  • Interface problems and fluid-structure interactions
  • Problems posed on moving domains (ALE and Fully Eulerian approaches)
  • Fluid-structure interactions and contact
  • Computational fluid mechanics
  • Multi-scale problems in space and time
  • Biomedical applications

Recently, I have also started working in the field of Scientific Machine Learning, i.e. the combination of classical numerical methods and machine learning (in particular artificial neural networks).
