Academic and Professional Background


Current Research and Publications / Selected Publications

  • Mammalian reproduction
  • Endocrinology and its links with immunology
  • Deer lactation and antler biology
  • Climate stress in dairy cows
In particular:
  • The role of c-type natriuretic peptide (CNP) as a potential marker for disorders of bone growth in children with the Christchurch School of Medicine.
  • The role of CNP during pregnancy and in brain function.
  • The biology of lactation in red deer hinds and the hardening process in bones and antlers.
  • The effects of climate stress on thermoregulation in lactating dairy cows.
