Biographical details

Angela graduated with a BSc (Hons) from the University of Melbourne, co-majoring in Marine Biology and Environmental Science. She completed a PhD on parental effects in broadcast-spawning marine invertebrates at the University of Queensland with Prof Dustin Marshall, during which time her interests shifted from Marine Science to Evolutionary Ecology. After her PhD, she moved to Sydney to work with Prof Russell Bonduriansky at UNSW, investigating mechanisms of non-genetic inheritance in the neriid fly, and was subsequently awarded an ARC DECRA Fellowship 'More than meets the egg: environmental effects on sperm quality, sperm competitive success, and offspring fitness.'In 2016, Angela was awarded a Postdoctoral Fellowship from The University of Sydney, funded by a bequest from the Mabs Melville Trust to the Faculty of Veterinary Science. She is currently investigating how environmentally-induced variation in seminal fluid influences animal reproduction.

Research interests

My teaching and research experience fall generally into the field of evolutionary ecology, with a particular focus on non-genetic inheritance and gamete plasticity. I am interested in environmental influences on male reproductive success, and whether changes in sperm and seminal fluid quality can influence the growth and survival of offspring.

My innovative research has already yielded a series of truly novel and exciting contributions to our understanding of male and female reproductive strategies. For example,I have shown that sea squirts produce more competitive sperm when surrounded by lots of other sea squirts, but that eggs fertilized by these competitive sperm are less likely to hatch into larvae. I also discovered that the diet of a female’spreviousmating partner (i.e. not the father!) can influence the size of neriid flies, a phenomenon known as telegony. Most recently, I have broadened the scope of my research to include applied human and animal reproduction, testing whether evolutionary ideas can be used to improve health outcomes.

Current areas of research:

  • Male reproduction
  • Paternal effects
  • Sexual selection
  • Sperm competition
  • Environmental effects on sperm and seminal fluid
  • Nutrition and ageing
