Research Interests

My research is primarily aimed at understanding of how individual behaviour and ecology interact to shape social structure, and the consequences of this for social processes (such as contagions) in societies. I enjoy collaborating across various topics in biology and beyond, such as using virtual systems to understand behaviour, assessing how sociality relates to health in wild mammalian populations, developing models of assessing the spread of conservation initiatives, and working with biomedical researchers in implementing big datasets to assess human health in relation to activity patterns.

I graduated from Sheffield University in 2012 and moved to Oxford to begin my DPhil investigating social networks in natural populations. I then undertook an EGI Research Fellowship also based at Oxford University’s Zoology department, joined Merton College as a Junior Research Fellow in October 2017, and was awarded a BBSRC Discovery Fellowship Grant in March 2019.
