Dioni Cendón from ANSTO joins the CWI team

Posted 19 December 2011

Dioni Cendón conducting fieldwork

Hydrogeochemist Dioni Cendón loves the least abundant parts of water, small traces of interactions with rocks or living things that can be used to follow their path in the hydrological cycle.

Already an adjunct member of the UNSW School of Biological, Earth and Environmental Sciences (BEES) at UNSW, Dioni has now joined the CWI research centre, which spans research in Science and Engineering.

Usually, Dioni can be found within the Institute for Environmental Research at the Australian Nuclear Science and Technology Organisation (ANSTO), where he is a task leader for 'Isotopes in the hydrological cycle', a research program at ANSTO designed to investigate ground and surface water connection, and the residence times of groundwater. This research utilises a number of key facilities available at ANSTO, especially the use of the Accelerator mass spectrometers for the analysis of 14C in dissolved inorganic and organic carbon within groundwater.

Dioni's research interests include the groundwater resources of arid, tropical, and humid landscapes, novel application of hydrochemical tracers, and the evolution of modern and ancient evaporite basins.

This breadth of interests and range of skills, especially in analytical chemistry, will complement the already large range of interests within the CWI team, and foster a closer collaboration between researchers at UNSW and ANSTO.
