Biography
Dr. Ahmed (Tia) Tiamiyu joined the Mechanical and Manufacturing Engineering department at the University of Calgary as an Assistant Professor in September 2021. Before then, Dr. Tia was a Postdoctoral Fellow in the Department of Materials Science and Engineering at the Massachusetts Institute of Technology, where he was also a board member of the MIT Postdoctoral Association. He received his doctorate and master's degrees from the University of Saskatchewan with a specialization in materials science, and a bachelor’s degree in metallurgy from the University of Lagos. Dr. Tia is both NSERC Vanier and NSERC PDF scholar. His research focuses on understanding the processing-structure-property-performance relationships in materials with an emphasis on materials synthesis and optimization for improved performance in extreme service conditions. Dr. Tia is currently developing the Materials Processing and Performance (MaPP) Lab at the University of Calgary to pursue different research projects based on his area of specialization.
