Summary

Current position

PhD candidate, NERC DTP, Faculty of Life Sciences (2018-present): exploring phenotypic and genotypic assortative mating in heterosexual and homosexual human couples, and the consequences for offspring viability.

Research interests

My previous research has focussed on how human attractiveness judgements are influenced by body morphology, especially limb proportions. My current work explores the related subject of realised human mate choice (i.e., who do people actually take as mates, rather than who are they attracted to). I have outside interests in conservation science and the use of experimental and quantitative methods in understanding conservation decision-making. 

Current research 

My work consists of several related projects. First, I am testing assortative mating for facial characteristics (shape, structure, and colour) in human heterosexual and homosexual couples. In collaboration with Alexander Lattas and Stefanos Zafeirou from the Department of Computer Science, I am using state-of-the-art 3D imaging technology to create digital facial models of couples that facilitate quantitative comparisons. Second, I am testing more general phenotypic and genotypic assortative mating in couples from the UK Biobank, a large database consisting of >500,000 participants (including up to 50,000 couples). The primary goal of this project is to explore the influence of assortative mating on offspring viability (e.g., health, relative size), testing the hypothesis that the evolution of this common behavioural trait has been driven in part by selection for compatibility that leads to greater offspring fitness. Whether this is biological in nature (e.g., maintaining coadapted gene complexes) or social (e.g., matching for personality traits to improve cooperation) remains to be seen and will be explored where possible. 

These two projects are united by a secondary research objective, namely to explore non-reproductive human mate choice among same-sex couples (i.e., homosexuality). Specifically, my work will test whether homosexual and heterosexual mate choice follow similar patterns, offering insights into potential factors underlying the evolution of homosexuality. This work is part of a wider series of projects being undertaken in my lab, headed by Vincent Savolainen, on the evolution of homosexuality in non-human primates.
