MCGILL UNIVERSITY, Montreal, Canada; Ph.D. in Mining and Materials Engineering (2010) TSINGHUA UNIVERSITY, Beijing, China; B. Eng. in Materials Science and Engineering (2006) EXPERIENCE HIGHLIGHTS ECOLE POLYTECHNIQUE – Montreal, QC Post Doctoral Fellow – Functional Coatings and Surface Engineering Laboratory, 9/2010 to Present Key Contributions: • Characterized the mechanical and tribological behaviors of various coatings used to prevent wear and corrosion of metal seated valves, designed a matrix of different properties to facilitate the coating materials selection for different applications for Velan. • Led investigation and optimization of PVD / CVD coatings to enhance the wear and corrosion resistances of metal substrates. • Investigated the erosion mechanism of TiAlN coatings for MDS Coatings. • Devised a standard test procedure and corrosion cells to evaluate the corrosion resistance of aluminum sheets, identified the delamination issue of the polymer coatings on aluminum cans during punching process for Novelis. • Collaborated with Pratt & Whitney – Canada to assess high temperature wear behaviour of Ni-alloy materials and provided advice on the materials selection. • Created a new electrochemical test protocol used to evaluate corrosion resistance of mirrors for Guardian, slashing test time from several weeks to six hours. MCGILL UNIVERSITY – Montreal, QC Doctoral Research Assistant – Textures and Microstructures Laboratory, 9/2006 to 8/2010 Key Contributions: • Managed and coordinated a collaborative CRIAQ research project which involved NRC, Pratt & Whitney Canada, MDS Coatings and Bell Helicopter. • Co-designed standard tribo-corrosion test protocol and tester to assess the synergistic effect of corrosion and wear in situ. This instrument (Tribocorr) is commercially available in today’s market. • Created and introduced a series of Si and C-based multilayer coatings to effectively enhance corrosion and tribo-corrosion resistance of stainless steel 410 substrate by a factor of ~2700 and ~400, respectively; exhibited high-level potential in various industries including autos and oil pipelines. • Developed highly dense and well adherent hard TiN-based coatings, enhancing the corrosion and erosion resistance of stainless steel 410 substrate by a factor of 180 and 50, respectively. • Performed a variety of functions as a teaching assistant such as tutoring, grading, and leading laboratory / discussion sessions, refining leadership and communication skills.
