I am based in Samoa at USP’s Alafua campus and teach undergraduate biology courses. My research interests include assessing the biosecurity risks from exotic species using biological-ecological informatics and modelling approaches. My current research is aimed at informing biosecurity policy for protection of native environments and ecosystems from the harmful impacts of invasive species. I am also interested in studying the impacts of climate change on the distribution/spread of plant pathogens.
