I am a PhD student at James Cook University in Cairns, Australia and CSIRO Health and Biosecurity. I am exploring the genetic, behavioural and ecological factors limiting the success of invasive tropical fire ants (Solenopsis geminata) and yellow crazy ants (Anoplolepis gracilipes) in Northern Australia. I am interested in the ecology and population genetics of invasive species , invasive species management, biosecurity, and reproductive biology.
In my PhD project, I explore the processes influencing colony founding in the invasive tropical fire ant (Solenopsis geminata) and the yellow crazy ant (Anoplolepis gracilipes) in Northern Australia. Specifically, for S. geminata, I work on how biotic resistance and disturbance influence their establishment success and the effect of small genetic diversity during the colony founding stage. I also use genomics to determine the origin and invasion history of tropical fire ants. For yellow crazy ants, I work on worker reproduction and colony organisation. This project combines manipulative field experiments, laboratory experiments and population genetics (Next Generation Sequencing ddRAD, microsatellite markers). Solenopsis geminata and A. gracilipes are two of the world’s worst invasive species, but for which little is known about their basic biology. My PhD project helps understand the factors that make these species successful invaders.
How invasive species overcome challenges associated with low genetic diversity is unclear. Invasive ant populations with low genetic diversity sometimes produce sterile diploid males, which do not contribute to colony labour or reproductive output. We investigated how inbreeding affects colony founding and potential strategies to overcome its effec...

Originally distributed in subtropical areas, the Rose-ringed Parakeet was accidentally introduced to Europe through the escape of captive individuals. The bird is now established in several European towns such as the suburbs of Paris (Île-de-France region). In order to update the population size and distribution of the Rose-ringed Parakeet in Île-d...
