Research interests

Research Interests

  • Algebraic number theory:
    • Galois module structures, e.g. the structure of the ring of integers of a number field as a Galois module, or of its unit group, or of the Mordell-Weil group of an abelian variety over a number field;
    • Arithmetic statistics, especially the Cohen―Lenstra heuristics on class groups of number fields and their generalisations;
    • Arithmetic of elliptic curves over number fields.
  • Representation theory of finite groups:
    • Integral representations of finite groups;
    • Connections between the Burnside ring and the representation ring of a finite group;
    • Applications of the above to number theory and geometry.
  • Geometry and topology:
    • Actions of finite groups of low-dimensional manifolds.
