Hidden feedbacks in population community dynamics, with help of size-structured modelling approaches


Research interests

I study the dynamics of marine ecosystems with emphasis on the roles of individual life-history, species interactions, fisheries, and parasites. Ecologically diverse, these subjects share some crucial aspects: energy is the common currency for organismal interactions and low-level processes shape high-level dynamics. I use mathematical modeling to study interactions and feedbacks, within and between species.

My research questions revolve for example around the mechanisms that lead to population collapses of Atlantic cod, how size-structure in fish populations shapes the top-down and bottom-up regulation in marine ecosystems, and how predation can influence the size-structure of host species to the benefit of parasites.

My scientific approach and expertise are focused on the conceptual and theoretical aspects of research. At the same time, I study ecological questions with direct implications for real-world systems and I rely on the insights from empirical research to stay grounded with the fundamental ecology of these systems. The most beautiful science bridges various modes of research and integrates conceptual levels.
