Background
2010-present postdoctoral research associate, Australian Centre for Microscopy and Microanalysis (ACMM), The University of Sydney, NSW 2006 Australia

2006-2010 Long-term guest scientist, Institute of Solid State Research and Ernst Ruska Centre (ER-C) for Microscopy and Spectroscopy with Electrons, Research Centre Juelich, Germany

2005-2010 doctoral student, Institute of Materials Engineering, University of Siegen, Germany

2002-2005 postgraduate student, School of Material Science and Engineering, Dalian University of Technology, China

1998-2002 undergraduate student, School of Material Science and Engineering, Dalian University of Technology, China

Current research
Dr Xia is working with Prof. Simon Ringer, Dr Gang Sha and Prof. Zhiguo Chen (Central South University, China) on “Control of microstructural evolution and properties in advanced aluminium alloys”. The aim of the project is to achieve a fundamental understanding of microalloying in Al alloys by using high-resolution transmission electron microscopy and atom probe microscopy techniques.

Other Research interests
Conventional and high-resolution TEM investigations on bulk and film materials; In situ TEM investigation on nucleation and growth mechanisms of nanomaterials; Synthesis, characterization and properties of nanomaterials; Nanofabrication of nanomaterials.
