Originally from Singapore, Dr Sivarajan began her academic journey in Melbourne, completing a Bachelor of Science at The University of Melbourne. She later relocated to Perth, where she earned her Doctor of Dental Medicine (DMD) from The University of Western Australia. During her dental training, she co-authored a research article titled “An Analysis of the Timing and Materials Associated with Pulp DiseaseFollowing Restorative Dental Treatment”, which was published in the International Endodontic Journal. Her career began in Albany, WA, where she gained valuable experience in regional dental care. Back in Perth, she worked across public and private sectors, building a versatile, patient-focused skillset. Over time, she developed a strong interest in sleep-related breathing disorders and chronic facial pain, prompting further postgraduate study. She completed a Master of Science in Medicine (Pain Management –Orofacial Pain) at The University of Sydney, with advanced training in assessing and managing facial pain, temporomandibular disorders, and sleep-disordered breathing from a dental perspective. Dr Sivarajan is an active member of the Australian Dental Association and remains committed to professional development, regularly attending national and international training in Dental Sleep Medicine and Orofacial Pain. Her practice combines clinical excellence with empathy, offering tailored care aligned with current research and best practices.
