Associate Professor Sumit Raniga is an academic orthopaedic surgeon with a background in molecular medicine and biomechanics. 

He is the author of numerous scientific publications in international peer reviewed journals. He is the first and only fellow of the Royal Australasian College of Surgeons to be awarded the prestigious Charles S. Neer award for research in the field of shoulder surgery by the American Shoulder and Elbow Society in 2016. This is the highest honour in shoulder surgery research in the world. 

Associate Professor Sumit Raniga has established and directs the MQ Health Translational Shoulder Research Program at Macquarie University. This is a world-class orthopaedic research program that focusses on basic scientific research that improves patient outcomes.

He leads a multidisciplinary team that enables an intensive collaboration between surgeons, radiologists, physiotherapists, biomechanical engineers, scientists and industry to improve patient outcomes through translational orthopaedic research. This world-class orthopaedic research program focuses on translational (basic scientific) research that improves prosthesis design, surgical techniques and rehabilitation to improve patient outcomes.
