Dr Andrew Studer is a research scientist with the Bragg Institute at ANSTO, leading the project to build the WOMBAT High Intensity Powder Diffractometer, one of the neutron instruments to operate at the OPAL reactor.

Qualifications and Achievements:

Instrument scientist for the Medium Resolution Powder Diffractometer (MRPD) at HIFAR (ANSTO)
PhD degree at the University of Sydney (1996), using time resolved interferometry to measure spectral line profiles in pulsed vacuum arcs

Dr Studer came to ANSTO after completing a PhD degree at the University of Sydney (1996), using time resolved interferometry to measure spectral line profiles in pulsed vacuum arcs. His previous work at ANSTO was as instrument scientist for the Medium Resolution Powder Diffractometer (MRPD) at HIFAR, assisting visitors (mainly carrying out AINSE-supported university research) and ANSTO researchers.
