Research interests

My current research interests in Reproductive Biology are concerned with the roles of hormones, growth factors, nutrients, novel biological products/extracts and environmental factors that influence reproductive success in mammals. The specific objectives of my research programme are aimed at:

  • Elucidating the genetic and molecular mechanisms by which mammals such as rodents, rabbits, possums and ruminants generate gametes for the production of viable off-spring.
  • Identifying the roles that somatic cells play in regulating the nutritional and energy requirements of germ cells and to elucidate the environmental influences that either enhance or retard these processes.
  • Determining the effect(s) of environmental contaminants, toxins, carcinogens and novel biological extracts on reproductive function using in vivo and/or in vitro bioassays.
  • Applying state-of-the-art biotechnologies to enhance and/or protect fertility of our endangered/valued species and to develop humane biocontrol methods for species that threaten our environment and economy. These technologies may include development of new diagnostics for monitoring fertility, environmental contaminants and reagents (e.g. recombinant hormones and/or vaccines) for enhancing or reducing fertility.
