Dr. Sek Shir Cheong is currently a postdoctoral research associate in the Lung Development and Repair group led by Dr Charlotte Dean at the National Heart and Lung Institute, Imperial College London. She joined Imperial in 2017 after completing a PhD in Molecular Genetics in Professor Alison Hardcastle’s lab in the Department of Ophthalmology at University College London (UCL). Her PhD study aimed to investigate the molecular genetics of developmental eye disorders using next generation sequencing technology, during which she discovered a novel genetic cause of a rare congenital anterior segment dysgenesis and proposed a genetic screening that improved the differential diagnosis of megalocornea and primary congenital glaucoma. Prior to this she graduated from University of Malaya with a First Class Honours degree in Genetics and Molecular Biology, and later completed a Master’s degree with distinction in Genetics of Human Disease at UCL.
Dr Cheong made a transition from eye to lung development for her postdoctoral research. Her current interests lie in the elucidation of the molecular mechanisms underlying lung development and repair. Aberrant lung repair is a hallmark of adult lung diseases, including Chronic Obstructive Pulmonary Disease (COPD) and Idiopathic Pulmonary Fibrosis (IPF). By using a combination of mouse and human molecular and cellular approaches both in vivo and in vitro, she investigates the planar cell polarity (PCP) and retinoic acid signalling pathways that play a pivotal role in lung development to identify potential components of these pathways that can be targeted to promote lung repair and regeneration.
Honours and Awards
Dr Cheong won the Professor E. Balasingam Gold Medal as the best undergraduate student in the Faculty of Biology. She was also awarded the competitive Commonwealth Scholarship to pursue a Master’s degree at UCL. Her 4-year PhD program was joint-funded by Graduate Research Scholarship and Overseas Research Scholarship from UCL. Her current postdoctoral fellowship is funded by the Royal Brompton and Harefield Hospitals Charity.
