Song Liu is an Associate Professor of Polymer Science & Engineering and directs the Biomaterials Synthesis and Medical Textile Surface Engineering Laboratory at the University of Manitoba in Winnipeg, MB. Dr. Liu earned a Ph.D. in Fiber and Polymer Science at the University of California, Davis.

Dr. Liu‘s research focuses on 1) the development of novel surface engineering techniques for chemically inert semicrystalline polymers; 2) the development of new biocidal and biocompatible materials; and 3) micro- and nano-encapsulation of bioactive agents for their targeted and controlled delivery. He has received over 1.35 M CAD in research funding as PI and close to 1 M CAD as Co-PI or collaborator from various granting agencies (including NSERC, CIHR, CFI and MHRC) for his pioneering work in exploring new durable and versatile surface modification techniques for chemically inert semicrystalline polymers, and developing new broad-spectrum biocides and “smart” polymeric materials. His research group has successfully developed a versatile polyester platform which can allow furnishing the surface with various bio-functionalities via “click” chemistry method in a spatially-controlled manner. This work lays an important foundation for well-controlled durable bio-functionalization of chemically inert semicrystalline polymers for their uses in medical devices such as anti-biofilm catheters, vascular grafts, drug release stents and wound dressings.

Dr. Liu’s research has had successful translation to industry with 5 patent applications, one licensing agreement and a second one in progress. He has won the 2012 Rh Award in Interdisciplinary Studies from the Winnipeg Rh Foundation in view of his leadership in interdisciplinary research.
