I joined the Hawkesbury Institute for the Environment as a Postdoctoral Research Fellow in Plant Biochemistry and Ecophysiology in September 2016, to work with Prof David Ellsworth and A/Prof Oula Ghannoum at the EucFACE facility. The project will investigate photosynthetic responses of Eucalyptus tereticornis trees under elevated CO2, with a specific focus on changes to and partitioning of the nitrogen pool within the canopy.
My research interests include plant responses to climate change, such as responses to atmospheric pollution (tropospheric O3), drought stress, heatwave and elevated CO2.
I started my research experience working on growth responses of several bio-indicators such as Nicotiana tabacum (Bel B, Bel W3), Phaseolus vulgaris L. and Petunia×hybrida to tropospheric ozone. This work was done under the supervision of Dr Klaudia Borowiak at the University of Life Sciences in Poznan (Poland).
I was awarded a PhD Degree at the University of Melbourne, School of Ecosystem and Forest Sciences in July 2015 under the supervision of Prof Michael Tausz and Prof Gerd Bossinger. In my thesis entitled "Antioxidant responses to drought and heatwave as markers for climate stress and adaptation", I investigated physiological and biochemical responses to stress of Acacia and Eucalyptus species adapted to contrasting habitats. I was particularly interested in the antioxidative and photoprotective defence system responses in young seedlings of Australian tree species under drought or heatwave conditions.
