I am a biogeographer working as a research assistant under the supervision of Dr. Damien Fordham at the University of Adelaide. I have a particular interest in the study of environmental changes and ecosystem equilibrium. In my previous studies I primarily analysed the associated influences of climate change and landscape modification on invasive species distribution with projections at different temporal scales. I was also involved in projects combining field and modeling approaches to estimate risk occurrence of a bacteria causing Lyme disease in Northern America.
As part of the Global Ecology Lab in the Environment Institute at the University of Adelaide, I am working on the ARC linkage project titled “An integrated tool for pest management: modelling range shifts for an invasive vertebrate in response to climate change”. One of my primary tasks is to develop a database that captures relationships between climate and environmental variables and rabbit demographic traits, abundance and disease dynamics across Australia.
My research interests are broad and include:Climate change,
- Climate change,
- Invasive ecology,
- Movement and landscape ecology,
- Spatial analysis,
- GIS and remote sensing,
- Ecological modelling,
- Wildlife management,
- Conservation planning.
We are all aware that the ecosystem and biodiversity are in tangible equilibrium, especially under the threats and influences of climate change, landscape modifications, and other anthropogenic factors. Species with general adaptive biological traits may benefit from these changes and exploit the opportunity to overcome barriers which previously restricted their distribution. Other species, more specialists in terms of spatial niche, may be more susceptible to these pressures and see their available habitat decrease rapidly. Interactions and dynamics between species are also likely to differ, while resources will be shared differently at various trophic levels. I am interested in studying the synergy between species distribution, the previously mentioned environmental factors, the tangible equilibrium of the ecosystem and biodiversity, and how it is possible to combine all these factors into a modeling framework for the purpose of wildlife management and conservation biology.
