Research Interests

I am interested in geometric topology, geometric group theory and dynamics. Topics I specifically studied include:

• stable commutator length, which

  • is a relative version of the Gromov-Thurston norm,
  • is dual to quasimorphisms,
  • captures geometric and dynamical information of (large) groups, and
  • can be used to find surface subgroups (in some hyperbolic groups for instance).

• mapping class groups of infinite-type surfaces,

  • which are essentially surfaces with infinitely generated fundamental groups,
  • such as the plane/sphere minus a Cantor set, which occurs naturally in dynamics (e.g. complex dynamics or kleinian groups).
