Research Interests

My research integrates morphological, biomechanical, functional, and developmental analyses to study how ontogeny, ecology, and phylogeny affect vertebrate design and function. This involves experimental and morphometric approaches to the analysis of form and function in organisms and comparative ecomorphological approaches to the study animal behavior. Research centers on vertebrate locomotion and feeding with current research in the lab focusing on the evolution of locomotion in frogs.

  1. Functional morphology and the evolution of vertebrate feeding and locomotion.
  2. Experimental and morphometric approaches to the analysis of form and function in organisms.
  3. Electromyography, kinematics, force measurement, and biomechanics.
  4. Life history, ontogeny, metamorphosis, patterns of neoteny and paedomorphosis in salamanders.
