Throughout my reaearch career, I have been particularly interested in acoustic communication and the social organization of animal societies, specifically in animal movements (automated radio-tracking) in relation to long distance signalling and territorial behaviour.
I have applied this previously in long-term projects on nightingales (vocal interactions and territorial behaviour, communication networks) and great tits (personality and communication, spatial behavour) as well as on other species like Carolina wrens and chaffinches (environmental acoustics, sound degradation and distance assessment) as well as white-browed sparrow weavers (cooperative breeding and dispersal, with Andy Young, Exeter). Furthermore, I have been using zebra finches in the lab over several years to address a range of questions on short and long term behavioural-, fitness-, life history-, and trans-generational effects of nutritional stress experienced during early development.
My current main project is on communication and social organisation in zebra finches in the wild (with Simon Griffith, Macquarie University Sydney) using novel solar-powered automated tracking technologies.
Moreover I coordinate a large interdisciplinary project (Eco2) on human-wildlife interactions and conservation behaviour in Egypt, funded by the WUR-INREF program (watch Eco2 movie) and since 2024 we are involved in a large project on human-wildlife conflicts around protected areas in Rwanda (CONNECT project funded by WUR-Global Sustainability program).
Students, feel free to contact me for thesis opportunities within the research lines (also see projects below) or if you have other ideas for a thesis project.
