Othman Nasir

Othman Nasir is an Associate Professor and Director of Undergraduate Studies in Civil Engineering at the University of New Brunswick. He holds a Ph.D. in Geotechnical Engineering from the University of Ottawa and is a licensed Professional Engineer.

Research Focus: Dr. Nasir develops numerical models simulating coupled thermal-hydraulic-mechanical-chemical (THMC) processes in geotechnical systems. His applications focus on nuclear waste containment in deep geological repositories, bentonite seal performance, gas migration in repository host rocks, and climate change impacts on geological storage systems. Additional work addresses cemented paste backfill technology for mining applications.

Technical Contributions: His research advances predictive capabilities for long-term repository safety through sophisticated simulations of glaciation impacts on sedimentary rocks, bentonite barrier behavior, and gas transport mechanisms. Recent publications establish modeling frameworks for assessing climate change effects on near-field rock properties in nuclear waste disposal.
