Dr Choy is a Chemical Pathologist whose research interests include the clinical utility of copeptin-based testing, laboratory investigations of endocrine hypertension, and web-based decision support to optimise diagnostic pathways in clinical biochemistry.

He obtained his medical degree from The University of Melbourne in 2009 and completed his specialty training in Chemical Pathology at Monash Health. In 2018, Dr Choy was awarded Fellowship of the Royal College of Pathologists of Australasia (FRCPA) and Fellowship of the Australasian Association of Clinical Biochemists (FAACB).

Dr Choy currently serves as Director of the Scientific and Regulatory Affairs Committee (SRAC) of the Australasian Association of Clinical Biochemists (AACB) and is Chair of the Scientific Programme Committee for the AACB Annual Scientific Conference 2026, to be held in Melbourne, Australia. He is also Chair of the Victorian Branch of AACB and holds an academic appointment as Adjunct Senior Industry Fellow with the Royal Melbourne Institute of Technology (RMIT) University.

He is a driving force in external quality assurance innovation, having developed two national EQA programmes in partnership with the RCPAQAP, supported by two RCPA Foundation research grants. Dr Choy is the author of more than 50 peer-reviewed publications and continues to contribute actively to advancing the governance, quality, and application of laboratory medicine through research, education, and national professional leadership.
