Short Biography

I studied at Durham University for my undergraduate degree (BSc Biological Sciences). Whilst at Durham I completed a laboratory project looking at whether mtDNA could be used for species identification in ancient seal specimens, and also undertook a literature review on the role of colouration in sexual selection. I then studied for my MSc in Ethology at Stockholm University with a Master’s project – supervised by John Fitzpatrick – that looked at male mate choice in a freshwater fish (Dermogenys collettei). Since 2019 I have been on the Interdisciplinary Biosciences DTP programme and will complete my DPhil project with the Pizzari Group.

Research interests

I am interested in the topic of sexual selection and more specifically in aspects of male-male competition that occur before and after mating. For my DPhil project I will investigate how males of lower competitive abilities strategically invest into mating opportunities to maximise their reproductive success. I will complete this work within the Pizzari Group and will use a combination of species, including the red junglefowl (Gallus gallus) and Drosophila spp. to address my research questions.
