Personal Profile

Dr. Nasiri holds a Ph.D. degree (2013) in Mechanical Engineering from the University of Waterloo, Waterloo, ON, and a MASc (2009) and BASc (2007) degrees in Materials Engineering, specializing in Welding from Sharif University of Technology, Tehran. His Ph.D. research at the Center for Advanced Materials Joining (CAMJ) in the University of Waterloo, entitled “Laser Brazing of Magnesium to Steel Sheet”, was funded by American Welding Society (AWS), and NSERC-Magnesium Network of Canada (MagNET).

Before joining Memorial University, he worked as a Sessional Lecturer in Mechanical Engineering Department of the University of Waterloo and was also a Laser Metallurgy Engineer and Materials Scientist at Summo Corporation, Burlington, ON. During this period (2015-2016), he mainly focused on developing Wobble-Fiber Laser Welding and an Electromagnetic Pulse Welding-Crimping Technologies for new Air Conditioning line design. Between 2014-2015, he worked as a Welding Engineer, and Canadian Welding Bureau (CWB) Certified Welding Inspector for Baumeier Corp., Cambridge, ON, where he developed and maintained engineering specifications, procedures, and processes related to laser welding, GMAW, GTAW and Non-Destructive Examination (NDE) of steels and Al alloys. From 2013-2014, he worked as an R&D engineer at the Center for Advanced Materials Joining at the University of Waterloo, where he conducted various research and development activities with different industrial partners, including Atomic Energy of Canada Limited (AECL), Litens Automotive Group, Lincoln Electric, and also Magnesium Network of Canada.

In July 2016, he joined the Mechanical Engineering Department of the Memorial University of Newfoundland, St. John’s, NL, as Assistant Professor. Currently, his research is focused on developing welding solutions for advanced high strength pipeline steels, corrosion resistance evaluation of welded components in H2S containing harsh environment, and thermo-microstructural modeling of advanced waveforms GMAW process.

His teaching activities include fundamental courses in materials science and engineering, welding and joining processes, welding metallurgy, fatigue and fracture mechanics, and industrial materials.

He is a member of American Welding Society (AWS) and Canadian Welding Association (CWA).


2016, 2014, and 2012: American Welding Society (AWS) Robert L. Peaslee Memorial Award,

2010-2013: Glenn J. Gibson AWS Graduate Fellowship Award.
