Dr Keong is a Malaysian-born, Cambridge-trained academic neurosurgeon with an interest in reversible brain injury. In addition to obtaining a Certificate for the Completion of Training (CCT) in the UK, she was awarded MPhil and MD degrees from the University of Cambridge. For her MD, she received the Raymond Horton-Smith prize (founded 1900) for best thesis. Prior to relocating to Singapore, Dr Keong successfully applied for a Transitional Award Grant from the National Medical Research Council of Singapore to fund a longitudinal MR imaging study, SERENDIPITI, in which cross-correlations between normal pressure hydrocephalus (NPH) and secondary hydrocephalus (post-trauma and intracranial haemorrhage) are being sought. She has research interests in clinical interventions to modify disease outcomes. She was the Principal Investigator of the SILVER trial, a double-blind randomised controlled study, which produced Class I evidence for the reduction of infection using silver-impregnated external ventricular drains.
Her focus is on acute-on-chronic reversible brain injury and developing neuroimaging biomarkers using Diffusion Tensor Imaging (DTI) methodology to characterise white matter injury patterns remediable with surgical intervention. She is involved in scoring strategies for risk stratification, early diagnosis and prognostication of mild-to-moderate Traumatic Brain Injury (TBI), as well as translating cognitive neuroscience into learning micro-interventions.
