I am a behavioural ecologist intrigued by the profound variation in how different species specialise on resources. For my PhD at the University of St Andrews (2018), I studied the foraging ecology of tool use in New Caledonian crows. I thoroughly enjoy fieldwork in remote locations into little-understood systems and species. I take great pleasure in working alongside resident communities and in doing so incorporating their cultural values and the associated logistics of the local environment into the research plan. My keen interest in the natural world originates from my childhood in rural Tanzania.

I joined the FitzPatrick in March 2019 as a postdoctoral fellow, where I am hosted by Prof. Claire Spottiswoode. I research the ecology and evolution of the remarkable mutualism between human honey-hunters and Greater Honeyguides ( My main focus is on understanding the human cultural variation that sustains human-bird cooperation, such as the calls ‘honey-hunters’ use to communicate with honeyguides. I employ an interdisciplinary approach to address my research questions, integrating ideas and methodologies from a variety of academic disciplines such as biology, anthropology, linguistics, as well as citizen science.
