A/Prof Samuel Chong joined the Department of Paediatrics, Yong Loo Lin School of Medicine, NUS as a Senior Lecturer in 1989 and became Associate Professor in 2003. He is the Director of the Preimplantation Genetic Diagnosis Centre at the Department of Obstetrics and Gynaecology, NUH. He also serves as Scientific Advisor to the Molecular Diagnosis Centre and the Clinical Cytogenetics Service of the Department of Laboratory Medicine, NUH.
Dr Chong received his undergraduate education at NUS and graduated with a BSc degree with honours in 1986. That same year, he left Singapore to pursue a Master’s degree at the University of British Columbia in Vancouver, Canada, under a CIDA (Canadian International Development Agency) scholarship. In 1989, he moved south to the United States of America to pursue further scientific training at the Baylor College of Medicine in Houston, Texas. While there, he stumbled upon and fell in love with the fascinating field of human and molecular genetics. He successfully defended his graduate thesis and was conferred the PhD degree in 1994.
He joined the National Human Genome Research Institute, National Institutes of Health in Bethesda, Maryland, as a Visiting Fellow in 1994. In 1995, he was concurrently appointed as Research Instructor at the Institute for Molecular and Human Genetics and Department of Paediatrics, Georgetown University Medical Centre, in Washington, D.C..
In 1997, Dr Chong moved to the McKusick-Nathans Institute of Genetic Medicine at the Johns Hopkins University School of Medicine in Baltimore, Maryland to take up an appointment as an Assistant Professor with a joint appointment in the Department of Gynaecology and Obstetrics.
At the turn of the century after more than a decade away in North America, Dr Chong returned to Singapore to re-join his undergraduate alma mater as a faculty member and he has been there ever since. His research interests are in finding innovative solutions to molecular diagnostic challenges.
His research interests revolve around developing innovative molecular toolkits for preimplantation, prenatal and postnatal diagnostic testing and screening of challenging genetic and genomic disorders. He has published more than 150 papers in local, regional, and international journals. He also teaches undergraduate life sciences students in human genetics and genomics.
