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.

Currently, I am completing a Masters in Data Science with the University of Adelaide, demonstrating and mentoring in 1st, 2nd, 3rd year Science subjects and developing learning and teaching from participating in the University of Adelaide's ADEPT modules.

I have worked for TERN SuperSite and Ecosystem Processes OzFlux. Data contributes to Global datasets of Fluxnet (Calperum, Site ID: AU-Cpr) and NASA's Ecostress mission. 







Tower weather, wind direction and speed

Fluxes in carbon dioxide, water and energy

Soil heat flux, moisture and conductivity

Leaves and their carbon are the broad impacts of my research. The monitoring of growth in the forests and crops would be regularly recorded by measuring leaf area index, the vegetation cover on forests and crops. The monitoring can be done from space with satellites or drones, the later, I have just qualified as a pilot to fly. 

Integral to my career has always been statistics, I am currently up-skilling with a Masters in Data Science to be able to handle satellite big data. I like to support students in their experimental design and statistics.
