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).
