Her primary work explores ethical issues in the translational application of emerging technologies in genomic medicine and healthcare services, including reproductive technologies, prenatal screening and diagnosis, and newborn screening. In her doctoral work, she employed a mixed method study, looking at the public health and social implication of non-invasive parental test (NIPT) screening for chromosomal aneuploidy in the two-tiered healthcare system. At present, she is collaborating with Hong Kong Children’s Hospital to explore public receptivity towards the storage of dried blood spot cards and whole-genome sequencing newborn screening.
