My PhD (2000-2004) with Professor Steve Tyerman, Dr Peter Anderson and Dr Molly Whalen from Flinders University, measured salt and drought tolerance ecophysiology of a natural hybrid of Eucalyptus largiflorens, called Green box.
This tree survives the harsh conditions on the Chowilla floodplain of the River Murray. The aim was to select trees for revegetation by screening seedlings with traits and AFLP DNA markers.
Traits were leaf carbon and nitrogen and the abundance of their natural isotopes (13C and 15N), and specific leaf area.
Rates of photosynthesis, transpiration and stomatal conductance were also monitored for calculation of water use efficiency and occurrences of non-stomatal conductance indicative of plants ability to cope with water/salt stress.

My Postdoctoral research (2005-2007) at Bangor University in Wales with Prof Davey Jones, Prof Gareth Edwards-Jones and Dr Paul Hill, formed carbon budgets for vegetable production in the UK, Spain and Uganda.
Components were soil respiration, plant biomass and soil organic matter and soil parameters for the DNDC (denitrification and decomposition) model.

I am interested in plant physiology, particularly of Eucalypts and carbon and water ecosystem balance. I am now developing as an educator (ADEPT). The last three years I have written articles for Phytogen, Australian Society of Plant Scientists (ASPS) newsletter. I have just commenced as Environmental and Ecophysiology: Global Change Representative.
I worked for seven years on the Calperum Mallee flux tower, Calperum Station near the Chowilla floodplain and Renmark, South Australia. The tower records data to a website : http://calperumchowilla.wordpress.com Click on site data and Calperum data to see updates every 6 hours.
