My research focuses on these deficiencies with the primary objective being the advancement and integration of state-of-the-art numerical modelling techniques with innovative geotechnical field measurements. The scope of this work is relevant to many problems relating to both surface and underground rock engineering problems, with emphasis being directed towards massive rock slope failures, both in the context of natural hazards (e.g. massive rockslides) and engineered rock slopes (e.g. open pit mine slopes), as well as tunnelling, underground mining, petroleum geomechanics (hydrofracing) and nuclear waste disposal.
