Biography

Higham lab website 

Note: I am on sabbatical until July 2018 as a Humboldt Fellow at the University of Freiburg and the Museum Koenig in Bonn, Germany.

My lab focuses on the origin and evolution of innovations, integration, and complexity, with a strong emphasis on the ecological context of organismal function. To do this, we integrate biomechanics, comparative physiology, comparative evolutionary methods, and ecology. This naturally combines organismal approaches with sophisticated laboratory techniques. Examples include the functional and evolutionary consequences of gaining and losing adhesion among geckos, the integration of feeding and locomotion among fishes and snakes, the neuromuscular basis of locomotion among anoles and geckos, and the dynamics of tail autotomy among geckos. Our fieldwork is conducted in a number of places, including the Bamfield Marine Sciences Centre in British Columbia, Gobabeb in Namibia, South Africa, Nouragues in French Guiana, Trinidad & Tobago, and in the southwest USA.. 

Past and current research initiatives include:

  • The adhesive interactions between geckos and plant surfaces
  • The biomechanics and evolution of gecko locomotion
  • The integration of locomotion and feeding in fishes and snakes
  • Muscle dynamics and biomechanics of vertebrate locomotion
  • Biomechanics and the origin of species
  • The neurobiology and biomechanics of tail autotomy in lizards
  • Physiology, biomechanics and evolution of predator-prey interactions in vertebrates
  • Hydrodynamics and biomechanics of suction feeding in fishes
