Dr Greg Guerin
Analysis & Synthesis Lead
School of Biological Sciences
Faculty of Sciences, Engineering and Technology
Greg is a terrestrial plant ecologist with over 15 years post-PhD professional experience in community ecology, macroecology and ecosystem monitoring. He has described 20 new plant species, mapped centres of plant biodiversity, and modelled the impacts of climate change on Australian ecosystems.
As the 'Analysis and Synthesis Lead' for TERN Ecosystem Surveillance, Greg provides analytical support for effective field monitoring of the Australian environment and develops open-source software (maintainer of the ausplotsR package) for extraction, analysis and visualisation of national ecosystem monitoring data from TERN AusPlots sites.
Greg has published over 70 peer-reviewed journal papers, plus many reports, conference items and book chapters, and he referees regularly for >40 international journals.
As Director of OUTLIER at the University of Adelaide, Greg coordinates specialised ecological and environmental data analysis and statistical review services to support industry and government, as well as the consulting and education sectors.
