Dr. Choy’s main research interests include:
(1) Development of novel molecular diagnostic strategies and innovative applications of molecular analysis tools in prenatal diagnosis. My current research focuses on the development of the genomic technologies including chromosomal microarray analysis (CMA) and Low-pass whole genome sequencing (Low-pass WGS) for prenatal diagnosis and reproductive medicine.
(2) Developmental genomic: Applies state-of-the-art technologies in genomic medicine to study the chromosome structure variants (including copy number variation and chromosomal re-arrangements) in human and to study the function of human genome by understanding the molecular mechanisms of normal and abnormal fetal development with particular focus on birth defects and neurogenetics.

Research Interest:
