LIU Chao
Research Associate Scientist

Chao Liu is an Research Associate Scientist at Southern University of Science and Technology (2019-present). Chao received his Bachelor of Applied Science in Engineering Science from University of Toronto (2008), in Canada. He received his Master of Applied Science in Mechanical Engineering (2010) and PhD in Biomedical Engineering at the Institute of Biomaterials and Biomedical Engineering, University of Toronto (2016). Chao has completed a postdoctoral fellowship at New York University with joint appointment from the Department of Biomedical Engineering and Department of Orthopedics at NYU Langone Health Medical Center. Chao’s research interests include the mechanobiology of stem cells, tissue engineering of bone tissue for regenerative medicine applications, and biomechanical functional implants.

Research Interests
Stem cell tissue engineering using mechanical forces and scaffolds in the musculoskeletal system.
(1) Utilize mechanical forces to alter bone forming (osteogenic) and blood vessel forming (angiogenic) stem cells that ultimately enhance bone regeneration
(2) Develop implants with functional macro- and micro-geometry to enhance the activity of angiogenic and osteogenic stem cells
(3) Develop 3D real-time cellular and molecular imaging modalities to observe the bone repair process in situ.
