Mark Ooi

I am a plant ecologist and much of my work encompasses the broad themes of seed ecology, fire ecology and global change biology, and particularly how changes to environmental factors can impact upon life-history traits and populations. This work is often applied to understanding related key ecological issues, including maintaining biodiversity and the impacts of climate change. I conduct my research in several systems including fire-prone heath and forests, arid ephemeral plant communities, and dune systems. I am involved in collaborative projects in Europe, China and Brazil, as well as with Australian researchers from the NSW Office of Environment & Heritage, University of Wollongong and Western Sydney University.

Most recently, as part of the NESP-funded Threatened Species Recovery Hub, I have developed several projects investigating the ecology of threatened species and how they respond to changes to the fire regime. 

I have a number of funded Honours projects available related to the conservation of threatened shrub species in fire-prone regions currently available. Please contact me if you’re interested in these or are interested in pursuing a PhD by emailing mark.ooi@unsw.edu.au
