Research in our lab revolves around fundamental questions in biology: Why do organisms age? How do they choose mates? More specifically, we are interested in the biology of ageing, the evolution of life histories and sexual selection. These questions are often intimately linked: for example, to understand sexual dimorphism in longevity, one has to combine evolutionary theory of ageing with sexual selection theory. We used to work on a variety of different organisms: nematodes, beetles, fruitflies, birds and humans, since our research is generally driven by the question rather than by the organism. Much of this work involves experimental studies in laboratory with small, fast-reproducing creatures but we also use privately or publicly available databases when it comes to populations of wild animals or humans.

The main focus of our current research is the biology of ageing, which is a fundamental and, as yet, unresolved issue in biology. We pursue this line of research both theoretically and empirically using experimental evolution, mutants, RNAi gene silencing, next-generation sequencing, behavioural assays and long-term studies of natural populations. Currently we are very interested in i) the developmental theory of ageing, and the relative importance of energy trade-offs versus function trade-offs in the evolution of ageing ; ii) the role of condition-dependent mortality in the evolution of ageing; and iii) sex-differences in ageing and lifespan.
