My main focus is selfish genetic elements and the ways that conflicts within the genome of individuals impact on the development and behaviour of individuals, the survival of populations, and in changing species at the landscape scale. In particular, I work on meiotic drive- selfish X chromosomes that spread by killing Y chromosome sperm, causing all female broods and distorting the sex ratios of whole populations. I try to understand the mechanisms that underly these drivers, and their ecological and evolutionary impacts on sex, speciation and survival.
A second theme is why some females choose to mate with only one male in their life, while others may mate with dozens a day.
More broadly, I also work on sexual cannibalism in mantids and spiders with my ACCE student, Adam Fisher. I also collaborate with ACCE student Chloe Heys on trying to understand why parrots masturbate so much.
