 I looked at every biologist's favourite animal: the fruit fly  Drosophila melanogaster , to see what it can tell us about evolutionary theory. 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?

I have a PhD in evolutionary biology from the University of Oxford, specialising in evolutionary theory and animal behaviour.

 My research   published in the Proceedings of the Royal Society B   in 2017 shows that indeed, brothers are nicer to females than unrelated males, but only if those brothers grew up together in the same environment as larvae.

 For the rest of my PhD, I looked at kinship effects on other behaviours at different life stages of  D. melanogaster.  I completed my PhD from the University of Oxford in 2018 (D.Phil Interdisciplinary Biology) and data from my other thesis chapters is in preparation for publication.

 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.
