I lead research on evaluating the impact of coal seam gas (CSG) and coal mining on groundwater and air. At present I am coordinating research on assessing the impact of CSG developments in the Surat Basin and Condamine Catchments, and quantifying the extent of connectivity between the Great Artesian Basin and the lower Namoi alluvium adjacent to the Pilliga CSG development.
My major research activities include:
- measuring the greenhouse footprint of coal seam gas, coal mining, natural landscapes, agriculture and urban environments
- mapping connectivity between coal measures and fresh water aquifers using isotopes
- quantifying aquifer depressurisation impacts on sustainable water use and ecosystems.
Recently, we have made extensive measurements of the major greenhouse gases (carbon dioxide, methane and nitrous oxide) throughout NSW and Qld. This has been achieved using a combination of continuous measurements using a car mounted greenhouse gas analyser and by collecting ambient air samples for later analysis in our isotope laboratory. This research is affiliated with the UNEP Methane Science Studies.
In the Greenhouse Gas Measurement laboratory we can analyse the isotopic composition of carbon dioxide, methane and nitrous oxide gases. Isotope analyses help attribute the sources of greenhouse gases measured in ambient air samples and gases stripped from groundwater.
Summaries on our CSG related research are presented in our EGU abstracts:

I also undertake research on the effectiveness of water sharing plans, improving water use efficiency in agriculture, regional groundwater management, the evolution of alluvial sedimentary systems, and on karst landscape processes.
Goal 2 - End hunger, achieve food security and improved nutrition and promote sustainable agriculture
Goal 4 - Ensure inclusive and equitable quality education and promote lifelong learning opportunities for all
Goal 11 - Make cities and human settlements inclusive, safe, resilient and sustainable
Goal 12 - Ensure sustainable consumption and production patterns
Goal 13 - Take urgent action to combat climate change and its impacts*
Goal 15 - Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss
I have written educational pieces on the need for research on CSG in The Conversation and Australian Geographic, and I contributed to the recent NSW Chief Scientist and Engineer background reports and reviews on CSG.

The Connected Water Initiative Research Centre, UNSW Australia, is seeking high-quality international and domestic applicants to apply for PhD positions. Applicants must have a 1st class honours degree (or equivalent), or a higher degree (MSc or MRes) and evidence of research experience. The international scholarships are highly competitive. Ideally the candidate will have an outstanding undergraduate degree from a top 100 University on the QS, Times, or Shanghai Jao Tong rankings. The candidate will have one or more first author journal papers in a leading journal. All applicants must develop a short research proposal with their potential supervisor. International applicants must also meet English language qualifications.

For studies in the biogeosciences with particular reference to: the quantification of greenhouse gas emissions from wetlands, estuaries, urban settings, coal mining and gas production; measuring and modelling terrestrial biosphere-atmosphere fluxes of water, CO2, CH4 and N20; using stable isotopes as tracers, please send your resume to email@example.com
Over the next century there will be unprecedented pressures on the environment (particularly on water, soil and air) due to global warming and increasing population. There is a critical need to measure greenhouse gas emissions, so that their generation can be managed. Australia is large and we need many people involved to improve our understanding of water and gas movement throughout the landscape. Being involved in measuring water movement and sources and sinks of greenhouse gases is one way you can make a positive contribution to managing the impacts of global warming. UNSW is at the forefront of measuring gases and their isotopic compositions. Within our gas lab we have:
- Picarro G2132-i Analyser for δ13C for methane
- Picarro G1101-i Analyser for δ13C for carbon dioxide
- Los Gatos Research Isotopic N2O Analyser (site-specific δ15N, δ18O and N2O)
- Los Gatos Research Ultraportable Greenhouse Gas Analyser (CH4, CO2, H2O)
- Los Gatos Research dissolved gas extraction unit
We also have access to facilities within the Mark Wainwright Analytical Centre: http://www.analytical.unsw.edu.au
And we work closely with the Institute for Environmental Research at ANSTO: http://www.ansto.gov.au/ResearchHub/IER/
