Biography

Dr Kwong Seh Ling is an Assistant Professor in the Health and Social Sciences Cluster at the Singapore Institute of Technology (SIT) and a speech-language therapist specialising in dysphagia assessment and rehabilitation. She completed her PhD in Speech and Language Sciences at the University of Canterbury, New Zealand, where her doctoral research focused on high-resolution pharyngeal manometry and swallowing physiology. Her research contributed to advancing the understanding of upper oesophageal sphincter function and pressure generation during swallowing.

Alongside her academic appointment, Dr Kwong maintains an active clinical role at Tan Tock Seng Hospital, where she has practised since 2009. She established the High-Resolution Pharyngeal Manometry (HRPM) service at TTSH and continues to perform instrumental swallowing assessments including videofluoroscopic swallowing studies (VFSS), fibreoptic endoscopic evaluation of swallowing (FEES) and HRPM as part of clinical care and research.

Her research interests focus on advanced assessment of dysphagia, swallowing physiology, dysphagia rehabilitation, and the use of biofeedback technologies to improve rehabilitation outcomes. More recently, her work has expanded into food-based approaches for dysphagia management, including transitional foods and novel texture-modified food products. She also conducts research in health professions education, with a focus on the use of immersive technologies to support the teaching of anatomy and dysphagia assessment skills.

Research Interests

  • My research focuses on the assessment and rehabilitation of dysphagia, with particular interests in swallowing physiology and the use of advanced instrumental assessment techniques. My doctoral research examined swallowing function using High-Resolution Pharyngeal Manometry (HRPM), and I continue to investigate the application of HRPM, videofluoroscopic swallowing studies (VFS), and fibreoptic endoscopic evaluation of swallowing (FEES) to improve understanding of swallowing disorders. Current research interests also include dysphagia rehabilitation, biofeedback interventions, transitional foods, texture-modified foods for dysphagia management, and innovative approaches to healthcare education.

Current Projects
