PhD Scholarship Available

We have a PhD scholarship available to join our ARC-Discovery project studying the responses of grassland and pasture vegetation to heat and drought! Great opportunity to work with an amazing team including me, Elise PendallSally PowerDavid Tissue, our international collaborators Alan Knapp & Melinda Smith, and a group of outstanding post-docs and students. Interested? Contact me for further details!



New Heatwave Research


heatwave wtcWe know that the heat is uncomfortable for humans and animals, but how does our native flora fare? Our group was very excited to be part of an HIE research team studying how eucalypts cope with heatwaves, using our unique whole-tree chambers.

The research is published in Global Change Biology. Read the media coverage on or the Guardian. (I’m told it was also in The Australian .. but that’s paywalled)

New ARC Discovery Project

We are very pleased to have been successful in the 2018 ARC Discovery round. Our project “Brown is the new green: grassland responses to heat and drought”  aims to improve our ability to predict grassland productivity in hot & dry conditions with a better understanding of physiological drought tolerance and leaf browning. My co-CIs on this exciting new project are Prof Elise Pendall, A/Prof Sally Power, Prof David Tissue (all from HIE) and Profs Alan Knapp and Melinda Smith from Colorado State.

Dr Lu Yaojie

Lu’s PhD thesis, “Optimal and Competitive Stomatal Behaviour”, has passed examination with flying colours. Congratulations to both Lu and his primary supervisor Dr Remko Duursma! Lu has published on optimal stomatal behaviour already and has a second outstanding contribution on competitive behaviour in preparation.
