Mark Ooi is a Senior Research Fellow based at the Centre for Ecosystem Science, part of the School of Biological, Earth & Environmental Sciences at UNSW. His research interests include fire and plant (particularly seed) ecology. A lot of his work is focused on understanding the mechanistic responses of plant populations to the fire regime, threatened species conservation and the effects of climate change. Mark has developed strong collaborative links with government and conservation agencies and aims to communicate his research findings to on-ground managers and the community.

He has been involved in collaborative projects in Europe, China and Brazil, as well as with researchers from across Australia. Mark is an Associate Editor of the journals American Journal of Botany, Seed Science Research and the Australian Journal of Botany.
