About
Research in the Head Group focuses on the evolution, ecology and physiology of sexual reproduction. Specifically, we are interested in how the environment (social and physical) influences the ecology and evolution of reproductive traits and how interactions between the environment and reproductive traits can generate biodiversity and lead to speciation. Within this focus our research also addresses questions regarding coevolution both within species (i.e. between males and females) and between species (i.e. Hosts and sexually transmitted infections).
Our research incorporates a wide variety of methods (molecular techniques, quantitative genetics, physiological performance measures, experimental manipulations and field observations) to address these research topics from different angles. I have also worked on many study systems (e.g. lizards, fish, insects), always chosen to best address the questions at hand.

Deeply entrenched scientific beliefs that for more than a century have explained why more men than women are high achievers because of biology are not backed up by evidence, according to new research.
Lead researcher Dr Megan Head says her study shows sexually transmitted diseases can act as a mediator for sexual conflict, which occurs when the evolutionary interests of males and females don't align.
