Research Center of the Quebec University Hospital-Laval University (Postdoc) Faculty of Dentistry Université Laval Québec, Canada 09/2017- Present Project 1: Pre-clinic research on modified textile based vascular prosthesis (sponsored by ST. JUDE MEDICAL).

Characterization of sealant modified commercial fabric vascular prosthesis (Vascutek and Cooley).

Histological and immunohistochemical evaluation of the textile based vascular explanted from dogs. Project 2: Electrical stimulation of human skin cells using flexible polypyrrole (PPy) for wound healing applications.

Preparation of fiber reinforced flexible PPy membrane.

Culture of cells relevant to wound healing in response to electrical stimulation.

Research Center of the Quebec University Hospital-Laval University (PhD) Hôpital Saint-François d'Assise Université Laval Québec, Canada 09/2012-10/2017 Project 1: Functionalized electrically conductive polymers and biomaterials for biomedical applications.

Template-assisted interfacial polymerization (TIP) was designed for the first time to prepare a soft and mechanically processable PPy membrane. The PPy membrane presents an excellent flexibility and processablity at both room temperature and -196 C. This membrane might be incorporated with fabric to enhance the mechanical properties for nerve repair, wound healing, and using as patches to rewire/repair infarcted heart tissue.

A novel reactivity-driven mechanism was proposed to synthesize the core-shell functionalized conductive polymer particles. A novel modular approach was proposed to immobilize biomolecules to a micro/nano structured surface via combination of the functionalized PPy particles and flexible PPy membrane. The functionalized conductive PPy might be introduced as a washable coating to fabric by covalent grafting. And this coating layer can also incorporate biomolecules to gain specific functions. Project 2: Research on artificial heart valves and pericardia (collaborated with Prof. Robert Guidoin)

Evaluation of clinically retrieved heart valves with textile ring in comparison with as-manufactured commercial heart valves to investigate the noncalcific structural deteriorations, emphasizing the importance of textile protection.

Evaluation of bovine, equine, porcine, kangaroo and donkey pericardia to seek potential alternative tissues suitable to manufacture the leaflets of percutaneous aortic valves.
