Background
Ibrahim Ogunsanya is a professor in the Department of Civil and Mineral Engineering, a professional engineer in Ontario, and a member of professional society addressing durability of materials and structures, including CIM (Canada), TMS (USA), IOM3 (UK) ACI (USA), RILEM (France). His research focuses on the durability and sustainability of materials and structures across several engineering sectors. He studies the processing-structure-property-degradation relationship to improve existing and develop new durable and sustainable materials, including ferrous (iron and steel) and non-ferrous alloys and superalloys (aluminum, nickel, copper, etc.), as well as cement and concrete. Over the years, the majority of his study has been on the durability and sustainability of reinforced structures because we continue to expose our infrastructures to harsher environmental conditions but ask more of their service life. Therefore, His role has been to select “appropriate” construction material (reinforcing bars, cement and concrete) combinations that solve our immediate and future socioeconomic needs. He is known for his research work on electrochemistry and corrosion.
