Research & Current Projects


Research Interests

  • Groundwater, especially karst hydrogeology
  • Geochemistry, especially organic and inorganic isotope geochemistry
  • Paleoclimate, especially reconstructing past climates from caves

 What does this really mean? Some exciting fieldwork in often remote places, and some exciting laboratory work involving expensive analytical equipment.

 

Current Projects

EXO2 advanced water quality monitoring platforms. With colleagues from the Wetlands, Rivers and Landscapes Research Centre, Ecology and Evolution Research Centre and Mark Wainwright Analytical Centre, we are experimenting with five state-of-art EXO water quality probes for the in-situ analysis of organic and inorganic water quality

Source – receptor analysis of lignin phenols and microbial tetraether membrane lipids in karst to quantify stalagmite biomarker proxies of vegetation and temperature change. Funded by the ARC, and with collaborators at UNSW and Curtin University, this Discovery Project is building capacity to undertake biogeochmiecal analyses which can also be applied to a wide range of sediments

A mass spectrometer to analyse carbonate isotope records of Australia's climate, soil and groundwater history’ Funded by the ARC, and in collaboration with colleagues from Newcastle University, University of Melbourne and ANSTO, with this infrastructure grant established our carbonate isotope facility (Thermo MAT253 with Kiel device) in 2011. https://www.connectedwaters.unsw.edu.au/news/massspectrometer.html

Precipitation-groundwater interactions over eastern Australia: climate change impacts at multiple scales. Led by colleagues in the Climate Change Research Centre, these ARC funded SuperScience Fellowships include research into soil and ground water processes.

Monitoring organic matter in drinking water systems using fluorescence spectroscopy: improved early warning, process optimisation and water quality. Led by colleagues in the Faculty of Engineering, this ARC Linkage Project is investigating the use of fluorescence in drinking water treatment in three states.

National Centre for Groundwater Research and Training. Within the NCGRT, I lead research teams investigating the use of speleothems to understand groundwater recharge and surface water – ground water interactions.
