I am an evolutionary biologist interested in fly sex and behaviour, studying for my PhD at the University of Oxford.

I achieved a first class degree in Biological Sciences from Oxford University in 2014, where I researched the effects of the invasive Harlequin ladybird on our native ladybirds. I was fortunate enough to visit the rainforests of Madagascar and Borneo during my undergraduate years to learn and practise tropical forest ecology.

I started my DPhil in Interdisciplinary Bioscience in 2014 also at Oxford University, researching sexual selection, kin selection and other cool bits of evolutionary theory under the supervision of Dr Stuart Wigby and Professor Stuart West.

In particular, I look at every biologist's favourite animal: the fruit fly Drosophila melanogaster. Sexual selection says males should aggressively fight with each other over access to females, but kin selection says brothers should be nice to each other. So what happens if brothers are fighting over females?
