Technical Research Interest:

I develop interdisciplinary programs that bring together the fields of veterinary medicine, human medicine, evolutionary and wildlife biology to explore the potential for a species-spanning approach to health. The potential for comparative clinical medicine and evolutionary medicine to yield new approaches and novel hypotheses for important health challenges is only now emerging. Some of the initiatives I have developed to expand the interface between these related but too often disconnected fields have included:

  • Conferences bringing physicians and veterinarians together to discuss the shared diseases of different species
  • Medical school course on comparative clinical medicine
  • Novel research initiative pairing UCLA medical students with UC Davis veterinary students to explore important health concerns relevant to both humans and animals
  • Evolutionary Medicine Month at UCLA - “Darwin on Rounds” Project
  • Develop undergraduate, graduate and medical school curriculum in evolutionary medicine
