Role In Centre

Veronica is a neutron scatterer and metallurgist. Her work has focused on the structural properties of materials from atomic bonding through to failure of components under extreme environments. She has conducted a number of neutron scattering experiments (SANS, Powder, TOF, Triple Axis), which she has correlated with mechanical properties (tensile, creep, fatigue), which she also measures. This has allowed her to link small phenomena such as interatomic bonding, heat treatment, synthesis methods and material aging to material strength, life and failure. The material she has worked with are high-performance material such as MAX phase ceramics, nickel superalloys, maraging steels, etc. The industries where her work is featured are in gas turbines for aerospace and power generation, as well as for novel clean energy technologies that undergo cyclic operation or harsh environments.

Short Biography

Veronica graduated from the University of Newcastle in 2008 with a Bachelor of Engineering (Mechanical) Honours and a Bachelor of Science (Physics). During her time as an undergraduate, she developed a strong interest in materials from the quantum level through to bulk handling. After graduating, Veronica then went and worked for Future Operations – Joint Operations Division at Defence Science & Technology. In this role, she was a Joint System Architect working in Distributed Maritime Electronic Warfare and also researching into CIED methodologies. Veronica left DST and returned to her PhD in interatomic bonding of MAX phase ceramics where she did experiments at ANSTO, Australia and LANL, Los Alamos USA. She was also invited to the Niels Bohr International Academy to present her work. After completing her PhD, Veronica worked at Swansea University in the Rolls Royce UTC on the mechanical properties of new aerospace materials. After 4 years in the UK, Veronica returned to Australia taking up a lecturer position at QUT in the school of Mechanical, Medical and Process Engineering.
