Biography

Dr. Andy Choi is an early career researcher who received his Ph.D. from the University of Technology Sydney (UTS) in Australia in 2004 on the use of computer modelling and simulation known as finite element analysis (FEA) to examine the biomechanical behavior of implants installed into a human mandible (jaw).

After completing his Ph.D., Dr. Choi expanded his research focus from FEA to biomaterials and nanocoatings, in particular, calcium phosphate-based nanomaterials for biomedical applications such as drug delivery and tissue engineering. Dr. Choi has extensive experience in the sol-gel synthesis of multifunctional bioceramic nanocoatings and nanocomposite coatings for dental and biomedical applications. His skills also expanded to the mechanical characterizations of these coatings using techniques such as nanoindentation.

In late 2010, Dr. Choi was successfully awarded the internationally competitive Endeavour Australia Cheung Kong Research Fellowship Award and undertook his post-doctoral training at the Faculty of Dentistry of the University of Hong Kong focusing on the application of FEA in dentistry and the development of calcium phosphate nano-bioceramics.
To date, Dr. Choi has authored 50 publications including 3 books and 24 book chapters on calcium phosphate, nano-biomaterial coatings, sol-gel technology, and finite element analysis in nanomedicine and dentistry.
At the moment, he is an associate editor of the Journal of Australian Ceramic Society (ISSN: 0004-881X) and as a guest editor for the Journal of Healthcare Engineering (Special Issue: Functional Coatings and Thin Films for Dental and Orthopedic Applications, ISSN: 2040-2295), and as a member of the editorial board in a number of dentistry and nanotechnology journals. In addition, he also served as a local Advisory Committee in the 16th Australasian BioCeramics Symposium (ABC) in 2016.
