What is the impact of environmental challenges on the genetic diversity within species?
We combine experimental and computational approaches to study the effect of environmental variation and stress on natural population. We use a range experimental models (Arabidopsis, Drosophila, ryegrass) to test hypotheses related to climate change and pesticide exposure.
Local adaptation plays a central role in maintaining genetic diversity through the selection of locally-suited genotypes. Across heterogeneous environments, many local optima coexist and differentially select genotype combination. This differential selction pressur provides the raw material for current and future adaptive challenges.View project
We have built a good understanding of how genes and genomes adapt over evolutionary times. However, how plants can carry a memory of previous climate exposure to the next generation remains an enigma. Given the pace at which plants will have to adapt to climate change, these transgenerational effects could be the key to successful short term adaptation.View project
Resistance to chemicals
The emergence of resistance to pesticide is evolution in action. Weed populations in Australia have been particularly good at emerging resistance to all the chemical they have been exposed to, providing a fascinating model for the study of evolution to a well-defined selective agent.View project
Climate Change-proof Restoration
Restoration projects have been instrumental at mitigating the effect of human perturbation. However, the perfect restoration scheme is yet to be designed. In particular, we are interested in using genomics tools to make sure the restoration will be successful, retains a maximum of genetic diversity and is climate change-proofView project
