Research interests

While I mainly focus on birds, I have broad interests within ecology and evolution. My DPhil project focus on how environmental variation affects natural selection across different spatial scales. To do so, I use data from the Wytham Woods Tit study, mainly focusing on the great tit (Parus major). From this study, we know when the different birds start breeding, how many eggs they lay and how many offspring the produce etc. This can be combined with data on tree-phenology in their territories, collected from high-resolution drones. In this way I can investigate how small-scale phenological variation affects different parts of the birds’ lives. In addition, I use data from multiple great tit populations across Europe to identify the spatial scale at which natural selection remains synchronous.

I have previously worked with questions related to extra-pair paternity in birds. I also have side-projects involving studies on effects of climate change on the common cuckoo. For my MSc I studied a metapopulation of house sparrows in northern Norway, a project I still am affiliated with. Please feel free to contact me if you have any questions about either of my projects or just want to discuss ecology!
