My major research focus is on policy that regulates environmental impact assessments. A key theme of this research is biodiversity offsetting - particularly, ways in which this tool can be harnessed to deliver better outcomes for people and biodiversity. I am also interested in landscape-level conservation actions in human-modified systems. Topics that I have examined include the use of thresholds of habitat loss to guide decision making, the implications of habitat loss for multi-species assemblages including the oft-neglected majority ('common' species), and regulatory mechanisms by which to conserve threatened fauna communities.
