Role at ANSTO
Dr Siobhan Tobin is an instrument scientist, co-responsible for the high intensity diffractometer Wombat. Her main research interest is the manifestation of magnetism in quantum materials such as topological semimetals, strongly correlated systems, and spintronic/magnonic candidates. She obtained her PhD in condensed matter physics from the University of Oxford, where she was a Rhodes Scholar supervised by Prof. Andrew Boothroyd. She welcomes enquiries from potential collaborators/neutron scattering instrument users in Australia and the Asia-Pacific region, especially those working on magnetic or thermo/magnetoelectric materials from the perspective of condensed matter physics, materials science or chemistry.
Siobhan has conducted experiments at central facilities including ANSTO’s Australian Centre for Neutron Scattering, the Institut Laue Langevin, the Diamond Light Source and the ISIS Neutron and Muon Source. Alongside her graduate studies, she was active in the University of Oxford Department of Physics as a tutor, laboratory demonstrator and teaching laboratory technician. She maintains a strong interest in teaching and science communication, having previously been involved in the Australian Physics Olympiad program.
Siobhan got her start in nuclear science techniques through the ANSTO Graduate Program 2017-2019, where she completed rotations in radionuclide metrology, neutron scattering sample environment and the nuclear analysis section (computational reactor physics). Prior to that, she completed an honours degree in physics at the ANU.
Expertise
