Research Interests

My research interest lies in the interface between development, ecology and evolution. I attempt to understand selective pressures on parental strategies and offspring developmental plasticity in natural populations to address its consequences for ecological and evolutionary processes. Two main patterns of research concern the evolution of sex allocation, i.e., resource allocation to sons versus daughters, and parental effects. Most of my work is conducted on European and Australian frogs and lizards and includes the following topics: evolution of developmental plasticity and maternal effects; phenotypic plasticity and local adaptation; reproductive strategies and sex allocation; evolution of sex determining mechanisms; sperm competition and post-copulatory processes; and population differentiation, inbreeding and disease resistance in amphibians
