Biography
I am a first year PhD student supervised by Dr Claire Spottiswoode. My research interests centre on brood parasitism in birds. I have carried out fieldwork in Africa (South Africa and Zambia), the Americas (Trinidad and Panama) and in the UK.
Research
My research focuses on the cuckoo finch Anomalospiza imberbis, which parasitizes several warblers in the family Cisticolidae. I conduct fieldwork in Choma, Zambia, where many aspects of brood parasite-host interactions have been studied. I focus on egg rejection behaviour in hosts and egg mimicry in parasites, aiming to understand the details and evolution of these complex behaviours and adaptations.
