Within the field of algebraic geometry, my research focuses more specifically on various aspects of the theory of linear algebraic groups over an arbitrary field.

  • Algebraic groups, pseudo-reductive groups, unipotent groups.
  • Cohomological theories.
  • Central simple algebras, quadratic forms.
  • Cohomological invariants.
