Jennifer J. Day

Ph.D. Geological Engineering

Office: Miller 312
Email: jjday@geol.queensu.ca
Thesis Topic: The influence of intrablock structure on rockmass strength​
Supervisors: Dr. Mark Diederichs and Dr. Jean Hutchinson

Research Interests

Jennifer’s research interests are currently based in rockmass characterization, both examining the issues with existing practices, and investigating more effective characterization methods with a focus on deep underground and high stress environments. This research is applicable to many applications including mining, tunnelling, deep geological repositories for nuclear waste storage, and other underground excavations.

Key words: Geomechanics, rockmass characterization, numerical modelling and analysis, laboratory rock strength testing, healed structures in rock (“intrablock structure”), rockmass classification, tunnel excavation and support design, underground and open pit mine design, nuclear waste repository design.

Brief Biography

Jennifer completed a B.Sc. in Geological Engineering (Geotechnical Option) at Queen’s in 2011, and a B.A. in Music with a performance focus at Queen’s (while working on graduate studies) in 2012. She entered into the Master’s program in September 2011 carrying a variety of work experience, including geological mapping with the Geological Survey of Canada in Baffin Island, geotechnical consulting with BGC Engineering Inc., and working as a junior geologist with Barkerville Gold Mines Ltd. She converted to the Doctorate program in May 2013 in order to continue her research at a more advanced level.
