Research interests:

My field is evolutionary ecology, with particular attention to how seasonality shapes ecological processes and evolutionary adaptations. Most of my work is in marine ecosystems and on birds, fish and zooplankton. I also have some projecets on terrestrial organisms and am interested in coastal ecology where marine and terrestrial processes and interactions often meet.

Central topics include: Life history theory, Phenology, Behavioral ecology, Population dynamics, Trophic interactions, Marine biology, Ecosystem connections & Ecological and evolutionary modelling.

You can visit the Seasonal Ecology Group for more information on the work I do together with students and collaborators. Publications are also available there, at ResearchGate or Google Scholar

I am in the steering group of bioCEED, a Centre of Excellence in Education, where I lead the work package on Efficient leadership of education, and coordinate a Forum for Educational Leadership in Biology.
