Dr Liang was trained as a pharmaceutical scientist and has since developed well-equipped research capabilities and leadership in the cross-disciplinary field of advanced drug delivery and nanomedicine. Dr. Liang completed his PhD in Pharmacy from the University of Queensland. His doctoral research theme was to develop nanoparticulate delivery systems for subunit vaccines, which spanned a range of fields including medicinal chemistry, pharmaceutical formulation, and immunology. Toward the end of his PhD, Dr Liang started to engage in research at the interface between polymer science and drug delivery and had gained hands-on experience in a variety of polymerisation and bioconjugation techniques. Upon completion of PhD, Dr Liang took up a postdoctoral position at UQ to investigate the biological interactions and toxicity of precisely engineered nanoparticles. This research had led to some key fundamental discoveries that resulted in several publications in the premium journals including ACS Nano, Nature Nanotechnology, Nanomedicines etc. During this time, Dr Liang was also a research teaching academic at School of Pharmacy and committed to teaching pharmacy undergraduates. After that, Dr Liang joined the Centre for Advanced Macromolecular Design in University of New South Wales, and his research was to develop a platform technology for the efficient delivery of albendazole towards better anti-cancer treatment. In 2011, Dr Liang accepted a lecturer position to establish drug delivery research group at the School of Biomedical Science and Pharmacy in University of Newcastle.
Dr Liang’s current research centres on advanced drug delivery and nanomedicine, which are at the interface of multidisciplinary fields including chemical & molecular engineering, materials science, chemistry, biotechnology and medicine. His research mainly involves developing novel biomaterials, utilizing self-assembly strategies to formulate biomaterials into desired nano-, micro- and macroscopic structures, and studying applications of these engineered structures for disease treatment and diagnosis.
I mainly teach into pharmaceutics and pharmacy practice within Master of Pharmacy program. In addition, I also deliver guest lectures into Bachelor of Biomedical Science program in the field of drug delivery.

Albendazole (ABZ), a well-established antiparasitic drug, has been shown to suppress tumor growth in a number of preclinical models of cancer. However, the low solubility of ABZ limits its use as a systemic anticancer agent. To enable systemic administration, we have formulated ABZ into albumin nanoparticles with a size range of 200-300 nm, which were cross-linked with glutaraldehyde to stabilize the nanoparticles and to introduce pH-responsive features. Drug release studies demonstrated that about 20% of ABZ was released at neutral pH within a week in comparison to 70% at slightly acidic condition (pH 5). Cellular uptake studies using ovarian cancer cells indicated that nanoparticles were internalized efficiently within 1 h of incubation. Further, cell proliferation results demonstrated that albumin nanoparticles alone showed no cytotoxicity to both normal and cancer cells. In contrast, the drug-loaded nanoparticles exhibited cellular toxicity and high killing efficacy to cancer cells compared to normal cells. Collectively, our results suggest that these albumin nanoparticles may hold great potentials as ABZ carriers for cancer therapy.
