Dr. Toyserkani holds the Canada Research Chair position in Additive Manufacturing (AM) and has over 20 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.

His lab is now the most comprehensive AM academic facility in Canada and one of the top 5 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.

He is an active steward in the AM field. He is the director of a Pan-Canadian NSERC Strategic Network entitled “Holistic Innovation in Additive Manufacturing (HI-AM)”, that brings together leading AM experts from seven top Canadian universities including University of Waterloo, University of Toronto, University of British Columbia, McGill University, University of Alberta, Laval, and, Dalhousie. Several international universities and 14 industrial partners are involved in this network. Further information can be found in this website: HI-AM | NSERC Network for Holistic Innovation in Additive Manufacturing (

He is a voting member of the American Society for Testing and Materials International (ASTM)-Committee F42, which is a leading committee in the development of standards for AM. He is also a member of the AM Advisory Committee of Advanced Manufacturing Supercluster (NGen) and was a member of the NSERC Selection Committee for Strategic Grant Applications (Advanced Manufacturing Target Area) from 2015 to 2018. He has been invited for >50 talks/panels in different countries. His research has been highlighted in many magazines and newspapers such as “The Globe and Mail”.

He has 18 granted/pending patents on different aspects of AM. He has actively transferred his innovative technologies to industry. Two start-up companies have been established that stem from his R&D programs.

His research is having a significant impact in the young AM field. He has published 135 AM-related journal articles (received >5800 citations as of October 2021). His research has been recognized through many awards/honours.
