Autobiography

I graduated in Animal Ecology at Göteborg University, Sweden, in 2000, went on to do a PhD in 2001 and finished in 2004. Between 2005 and 2007 I was a Wenner-Gren Postdoctoral Fellow at the University of Wollongong, Australia, where I continued to work on the evolutionary ecology of lizards and amphibians with a specific focus on sex allocation, sex determination, and maternal effects. I joined the EGI and the University of Oxford in late 2007 when taking up a Departmental Lectureship in Animal Diversity.

Research Activities

My research interest lies in the interface between development, ecology and evolution. I attempt to explore the links between environmental variation, phenotypic plasticity, and selection in natural populations to address their consequences for ecological and evolutionary processes. Two main areas of research concern the evolution of parental effects and sex allocation, i.e., resource allocation to sons versus daughters. Most of my work is conducted on European and Australian frogs and lizards.

My research is currently funded by the Australian Research Council and the Royal Society of London and addresses a range of topics including:

  • Evolution of developmental plasticity and maternal effects
  • Phenotypic plasticity and local adaptation
  • sperm competition and sex allocation
  • Evolution of sex determining mechanisms
  • sperm competition and post-copulatory processes
  • Population differentiation, inbreeding and disease resistance in amphibians

Other Information

I am a Wenner-Gren Fellow and a Fulbright Fellow. I received the 2009 Christopher Barnard Award for Outstanding Contributions by a Young Investigator.
