From 1993 to 1998, Metlyuk pursued a Bachelor of Science in Physics at the Lviv Polytechnic Institute. His undergraduate thesis, supervised by Professor Oleksandr Korytov, investigated the electronic properties of thin film semiconductors. The work earned him the institute’s Award for Excellence in Undergraduate Research.
In 1998, Metlyuk was awarded a scholarship by the Ukrainian Ministry of Education to pursue graduate studies abroad. He enrolled in the Ph.D. program in Applied Physics at the University of Toronto, Canada, under the mentorship of Dr. Alan Thompson. His doctoral research focused on the synthesis and characterization of two‑dimensional nanomaterials, particularly graphene and transition‑metal dichalcogenides. The Ph.D. was completed in 2003, and his dissertation, titled “Electron Transport in Layered Two‑Dimensional Materials,” received the Outstanding Ph.D. Thesis Award from the Canadian Association of Physicists.
Academic and Professional Career
Early Research and Postdoctoral Work
Following the completion of his Ph.D., Metlyuk undertook a postdoctoral fellowship at the Massachusetts Institute of Technology (MIT) from 2003 to 2005. Working in the Laboratory of Atomic and Solid‑State Physics, he collaborated with Professor Lisa K. Miller on the development of scalable fabrication techniques for graphene nanoribbons. The project yielded several high‑impact publications and led to the establishment of a joint research grant with the National Science Foundation.
In 2005, Metlyuk accepted a postdoctoral position at the National Institute of Standards and Technology (NIST), where he led a team studying the electrical reliability of nanoelectronic devices under extreme temperature conditions. His findings contributed to the design guidelines for next‑generation semiconductor manufacturing, influencing both academic research and industrial practices.
Faculty Positions
Metlyuk joined the faculty of the Department of Electrical Engineering at the University of Alberta in 2007 as an assistant professor. His appointment was extended to associate professor in 2012 and to full professor in 2017, reflecting his prolific research output and successful grant acquisition. In 2020, he accepted the position of Distinguished Professor at the University of British Columbia, where he directs the Nanomaterials Research Centre.
In addition to his university appointments, Metlyuk has served as a visiting scholar at several international institutions, including the Technical University of Munich (2014–2015) and the University of Tokyo (2018). He has delivered keynote lectures at more than 40 international conferences and has supervised over 25 Ph.D. students and 60 master’s students throughout his career.
