Research interests

As a population ecologist my research focuses on trying to understand variation in life-history traits and demographic rates within populations and link this to population level patterns and processes such as delayed density dependence. I use both theoretical and empirical approaches, and I am particularly interested in using and developing methods and statistical models to estimate (correlated) distributions of latent life-history traits within populations. This work is also highly relevant for selection processes in an evolutionary context, and I aim to contribute towards our understanding of the evolution of phenotypic plasticity in life-history traits.
