    LBMD invites research scientists from University of Alberta and University of Hong Kong

  • The Laboratory of Biomedical Materials and Devices (LBMD) hosted Professor Edmond Lou and Dr. Kelvin WK Yeung of the University of Alberta and University of Hong Kong, respectively, on October 10 at the Leoo Koguan Building.

    Professor Yufeng Zheng, the head of LBMD, invited Lou and Yeung to give talks on their biomedical research.

    Edmond Lou gives his talk

    Lou is currently an adjunct professor in the Departments of Electrical and Computer Engineering, Biomedical Engineering, Pediatrics and Surgery at  University of Alberta and is a research scientist of Alberta Health Services in Alberta, Canada. His research interests include wireless communication, embedded systems, bioinstrumentation, treatment and assessment of spinal deformity. In his talk, he reviewed the history of treatment for Idiopathic Scoliosis, and pointed out the difficulties that the current surgical intervention therapy faces. At present, the success and outcomes of surgery depend heavily on the skill and experience of the surgeon. In particular, the amount of force applied to correct the deformity of the spine is unknown. In his talk, Lou shared the development of a surgical tool set which can be used to monitor the applied forces from the orthopedic surgeons, to determine the forces distribution along the spine and to track the vertebrae displacement during correction. The goal of his research is to develop a pre-surgical planning tool to provide better treatment for scoliosis.

    Kelvin WK Yeung gives his talk

    Yeung’s talk focused on the study of a biodegradable polymeric-metallic scaffold used for bone tissue engineering. Yeung is currently an assistant professor in the Department of Orthopaedics and Traumatology at the University of Hong Kong. His research interests include surgical correction of scoliosis, memory alloys for biomedical use, and tissue engineering. To offer an alternative for traditional methods of bone replacement, his group has fabricated a biodegradable polymeric-metallic scaffold by incorporating magnesium (Mg) into Polycaprolactone (PCL), since magnesium is a biodegradable metal which possesses higher mechanical strength and is an essential mineral for cells. Their study aims to investigate the mechanical and in-vitro properties of the PCL-Mg scaffold.

    The Laboratory of Biomedical Materials and Devices (LBMD) is an interdisciplinary research group initiated and led by Professor Yufeng Zheng since 2004. The laboratory involves researchers from different academic backgrounds, including material science, medical science, chemistry and mechanical engineering. The group works extensively on biomedical materials and their applications in dentistry, orthopedics and interventional therapy. Starting from the fundamental microstructures and compositions of biomaterials, research interests of the laboratory have extended to the evaluation, design and development of biomedical devices and instruments.
