Research interests

My research focusses on understanding the ecological and evolutionary processes that determine the dynamics of biological populations. In this era of global climate change and large scale human induced habitat degradation, the pressure to respond adequately is stronger than ever. If animals are incapable of responding to environmental change, declines in numbers, and possibly extinctions, are inevitable. In my research I combine ecology and evolution to understand adaptations to rapid environmental change in the wild, and its effect on population dynamics.

As NIOZ postdoc researcher, I am part of the gull research team. I particularly focus on the link of individual specialisation and population dynamics of Herring Gulls and Lesser Black-backed Gulls. One of the questions I'm interested in, is what will happen with the gull populations in relation to changing fisheries at the North Sea, now discards will reduce in availability.

In the past, I have studied population dynamics of Black-tailed Godwits at University of Groningen with Prof Theunis Piersma. I focused on the role of agricultural intensification on godwit population characteristics such as vital rates and phenology. At University of Oxford (2016-2018), I have studied density-dependent life history selection in Soay Sheep and found that population fluctuations can maintain variation in life history traits.
