Biography

My research is related to rock mechanics, rock engineering design and numerical modelling. I have intensively researched and published on the use of discrete fracture network engineering, interaction between surface and underground mining, mechanical behavior of hard rock pillars, slope stability analysis, and applications of synthetic rock mass modelling. When applied, the findings of my research support more efficient rock engineering design and improve operational safety – an especially important consideration as mines are being developed deeper underground. I have worked for 10 years as a geotechnical and rock mechanics engineer for consulting companies in Ireland and Canada, providing consultation on aspects of both surface and underground rock engineering for mining and civil engineering project. To date, I have collaborated on more than 80 technical papers (peer-reviewed journals and conference proceedings).

Research Interests

Discrete fracture network modelling and analysis of fragmentation processes
