Research
Professor Darryl Tong’s main research interests include military and civilian trauma with a particular focus on ballistic injuries to the head, face and neck, sports-related concussion and subconcussive impact force research.
He also has interests in clinical and systematic review-based research in oral and maxillofacial surgery including dentoalveolar surgery,pathology, trauma, dental implantology, and other clinical aspects of the specialty. Of particular interest however is maxillofacial trauma and ballistic injury especially in theatres of conflict.
Professor Tong's PhD involved looking at war injuries of the face and jaws from an integrated historical and surgical viewpoint. Other research interests include forensic biology and sports medicine.
