Shenzhen Research Institute,
Department of Obstetrics and Gynaecology
Dr. Richard KW CHOY works in Department of Obstetrics & Gynaecology, The Chinese University of Hong Kong (CUHK), where he serves as Associate Professor as well as Director of Pre-implantation Genetic Diagnosis Laboratory of the same unit. Dr. Choy co-founded the Prenatal Genetic Diagnosis Centre and Pre-implantation Genetic Diagnosis Laboratory at CUHK, and has led a number of important milestones in Prenatal Diagnosis which include: A landmark study that established the role of chromosomal microarray analysis in fetus with high Nuchal translucency. He is an expertise in genomic medicine and molecular diagnosis. His main research interests focus on applying state-of-the-art technologies combined with innovative applications of molecular analytic tools to study the chromosome structure variants (including copy number variation and chromosomal structural rearrangements) in human. Recently his laboratory has establishthed the low-pass whole-genome sequencing method for explaining the implications of genome structural variation and its utility in clinical cytogenetics.
