Research interests

  • Geostatistics (mapping, statistics, water table, aquifer)
  • Hydrogeology (groundwater management, surface-groundwater interaction)
  • Hydrological resilience (hydrology, resilience, catchment modelling)


I have over 17 years experience in hydrological and hydrogeological research and consulting. My research focus is on detecting long-term change in catchment hydrological processes and drivers early enough so that society can be taken action. Central to this is understanding when and where catchments do and do not recovery from disturbances, such as droughts or land cover change. All of my research is focused on social-outcomes and I strive to place my research within Pasteur's quadrant (https://en.wikipedia.org/wiki/Pasteur%27s_quadrant)

I completed my Phd in 2009 on pioneering work on catchment resilience and multiple steady states (http://hdl.handle.net/11343/35439) and was subsequently awarded an Australian Research Council Post-doctoral Fellowship to continue this research.

More recently, I've been researching the use of statistics to identify catchments with multiple steady states. This research has also allowed considerably greater quantitative value to be derived from groundwater monitoring. Specifically, I've developed nonlinear groundwater time-series approaches for extrapolating and decomposing hydrographs and probabilistic geostatistical methods for mapping groundwater elevation. These tools have considerable practical outcomes and, in collaboration, they've been adopted by The Department of Environment and Primary Industries (Vic.), Power and Water Corporation (N.T.) and the Bureau of Meteorology - with the latter adopting the mapping techniques for the National Water Accounts.

I have or are supervising the following Phd students:

  • Dr. Vahid Shapoori: Statistical decomposition of groundwater hydrographs into climate and pumping impacts. (completed)
  • Ms. Emma White: Numerical evaluation of the effectiveness of groundwater management plans.
  • Mr. Sina Khatami: Quantifying equifinality in conceptual rainfall-runoff modelling.
  • Ms. Silwati Womera: Statistical estimation of flood recharge.
  • Mr Giancarlo Bonotto: Surface-groundwater modelling for better management of groundwater dependent ecosystems.
