Plasticity of lifespan in the honeybee & the disposable soma theory
This project investigates the plasticity of lifespan in the honeybee and the disposable soma theory.
Evolutionary genetics of sex, sexes and senescence (s3)
I study the evolutionary genetics of fundamental problems: the evolution of sex and recombination, sexes (anisogamy), senescence (ageing) and altruism (kin selection).
These questions are approached using comparative data analysis and mathematical modelling. As such, my work is purely computational, relying on statistical analysis and computer programming.
I have been modelling the coevolution of hosts and pathogens to test the idea that such antagonistic coevolution selects for recombination.
I have also been using data from the volvocince algae (Volvox, Chlamydomonas, etc.) to test theories about the evolution of anisogamy (sexes).
Another area of focus is using life table data from honeybees to determine whether the large differences in lifespan between queens and workers are due to the different hazards of their lifestyles or whether they are due to the adaptive plastic regulation of somatic maintenance.
How do we feed the world’s growing population? How do we save our wildlife from extinction? Got an idea that will build a brighter, greener world?
Australian high school students are invited to submit a short video about one of Australia’s big science challenges.
