Dr Nathan Webster is a Principal Research Scientist and the Group Leader of the Microbeam and Diffraction Group of the Characterisation Program in CSIRO Mineral Resources.

In 2008 he joined the Minerals division of CSIRO as a Postdoctoral Fellow, and stayed in this role until 2013 developing and implementing tools for the investigation of material formation under hydro- and pyrometallurgical processing conditions using in situ X-ray and neutron diffraction. In May 2013 Nathan began his role as Research Scientist – Diffraction within the CSIRO Mineral Resources Flagship, a role which allowed him to drive diffraction-based capability development and implementation within CSIRO, particularly in-situ studies.

He has significant expertise and experience in X-ray diffraction-based quantitative mineral and material phase analysis, including clay identification and quantification. He also has significant expertise and experience in in-situ diffraction analysis to characterise the evolution of mineral and/or material phase chemistry as a function of temperature, pressure and atmosphere.

Nathan is a former President of the Australian X-ray Analytical Association (AXAA,, is a past Chair of the Program Advisory Committee (PAC) for the powder diffraction beamline at the Australian Synchrotron, a past member of the User Advisory Committee (UAC) at the Australian Synchrotron, and CSIRO's past representative on the Australian Institute of Nuclear Science and Engineering (AINSE) Council.

Nathan has authored more than 70 journal publications, 1 book chapter, 6 conference proceedings publications, and has an H-index of 22. In addition, he has authored more than 80 reports for industrial clients.
