Pillar / Cluster: Engineering Product Development
Subburaj (Subbu) is an Assistant Professor in the Pillar of Engineering Product Development (EPD) at SUTD, where he leads Healthcare Engineering and Design Track and the Medical Engineering and Design Lab. He leads an inter-disciplinary research team with the goal of designing and developing medical devices, assistive technologies, image-based quantitative biomarkers, and computing tools (FEA / ML / AI) for diagnosing, monitoring, treating, and potentially preventing musculoskeletal disorders and disabilities (Osteoarthritis/ Osteoporosis / Scoliosis) by understanding bio-mechanical implications of these diseases and disabilities.
His research interest is on design innovation in medical devices, technologies, and methods for successful and active aging. More specifically on (1) biomechanical understanding of aging and its impact on the prevention, progression, and prognosis of illnesses, injuries, and associated disabilities; (2) developing effective early assessment and continuous monitoring systems, methods, devices, and tools to maintain health, well-being, and function and reduce the burden of age-related musculoskeletal fragility.
He collaborates with physicians and clinical researchers from Tan Tock Seng Hospital (TTSH), Technical University of Munich (TUM), Singapore General Hospital (SGH), and Changi General Hospital (CGH) to combine research and technical expertise to address real-life clinical problems affecting Asia-Pacific and the World.
Before joning SUTD, he did his postdoctoral work in Musculoskeletal Quantitative Imaging Research (MQIR) laboratory at University of California San Francisco (UCSF). At UCSF, he worked with a spectrum of clinicians (from radiology, orthopaedic surgeons, sports medicine, and physiotherapy/rehabilitation science) on characterizing magnetic resonance image (MRI) based bio-markers to understand the physiological and biochemical response of knee joint cartilage to physical exercise and acute loading. He has also developed and validated 3D modelling and quantification methods to study joint (hip/knee) loading pattern and contact kinematics in young healthy adults and patients with osteoarthritis.
