Research interests:

  • Adaptation and speciation in cave environments.
  • Evolution of behavioural consistency (animal personalities, behavioural syndromes).
  • Adaptive divergence in nine-spined sticklebacks (Pungitius pungitius): the effects of predation and competition.
  • Sexual selection in European green lizards (Lacerta viridis): visual and chemical signalling.
