A 4-year PhD position on modeling gas migration in bentonite-based engineered barrier for deep geological repository (DGR) of nuclear waste is now open in the Department of Civil Engineering at the University of Ottawa, Canada.  The successful applicant will: (i) develop suitable mathematical models to describe and predict gas migration in bentonite-based materials; (ii) validate the models against laboratory experiments and in-situ tests; (iii) numerically simulate gas migration through the buffer and shaft of a potential Canadian DGR. If you are interested in this PhD position, please send your CV and a motivation letter (email message) to Prof. M. Fall (mfall@uottawa.ca) by August 31, 2022.
