Biography
I have examined the evolutionary consequences of sperm competition for male and female reproductive physiology in house mice (Mus domesticus), at the whole organism and gametic levels. I have combined field based population approaches with experimental evolution in the laboratory, and used novel in vitro fertilisation (IVF) technologies to explore the hypothesis that sperm competition generates sexual conflict over fertilisation. Currently, I am interested in determining whether males and/or females use paternity biasing mechanisms to increase the production of male or female offspring under specific conditions. I also tend to explore the phenomenon of sexual conflict (misalignment of mother/sire interests) over sex allocation among offspring. My most recent investigations have extended to the native sandy inland mouse (Pseudomys hermannsburgensis). I intend to further develop my studies of native species in the future.
