Biography Summary

Dr. Toyserkani, who is a professor in the Department of Mechanical and Mechatronics Engineering, holds the University Research Chair in Additive Manufacturing (AM) and has over 17 years of experience in different aspects of AM research and development, from mechatronics AM system development to AM applications in medicine and engineering. He established the first AM laboratory at a Canadian university - the Multi-Scale Additive Manufacturing (MSAM) Laboratory – which focuses on the development of the next generation of AM processes and applications. With recent investments from FedDev Ontario and Ontario’s Ministry of Research, Innovation and Science (MRIS), worth $15.1 million, his lab is now the largest AM facility in Canada and one of the top 10 academic AM facilities in the world. His extensive experience in AM and leadership have allowed him to devote his academic life to addressing AM challenges holistically and promoting this strategic research area at the national and international level.

His research programs focus on next generation additive manufacturing processes. To this end, the lab explores novel techniques to develop advanced materials, innovative products, modeling and simulation tools, monitoring devices, closed-loop control systems, quality assurance algorithms and holistic in-situ and ex-situ characterization techniques.

He has six granted/pending patents on monitoring and real-time control of laser AM, AM technologies for embedding optical sensors within metallic structures, and AM of porous structures. He has actively transferred his innovative technologies to industry. To name a few, he transferred an AM process for personalized biodegradable biphasic porous scaffolds for bone substitutes, osteochondral, and cranial/ maxillofacial osteosynthesis applications to Mount Sinai Hospital and Sunnybrook Hospital (Toronto); and, a novel micro-scale AM for making advanced sensors to GE Aviation. Two start-up companies have been established that stem from his R&D programs. His work has been highlighted by major newspapers, such as “The Globe and Mail”.
