Awards

I am interested in the dynamics of multi-phase flows in volcanic conduits (kimberlitic and basaltic), and the climate impacts of early Cenozoic hyaloclastite volcanism and hydrothermal vents in the North Atlantic. I have set up a fluid dynamics laboratory at NOCS to investigate the dynamics of gas flow through porous media in both terrestrial and marine environments. This work has diverse applications including carbon capture and storage, flow around high-voltage cables, and understanding gas-particle interactions in pyroclastic flows.

Lecturer in Geology, Trinity College Dublin, Department of Geology

2008 - 2009

Responsibilities included preparing and presenting lectures, setting and marking coursework
and examinations, and co-supervising geology field courses. Course director of level 3 igneous petrology. Developed new lecture syllabuses and practical laboratory and mapping exercises for geology courses.

Working closely with De Beers Canada on the dynamics of dyke emplacement at Snap Lake Diamond Mine, NW Territories, Arctic Canada, to develop a geological model based on an understanding of dyke emplacement processes. Research included underground mapping of the architecture and structure of the ore-body, and analysis of geological data. Investigation of the geological controls on ramps and steps that occur in the dyke and which cause difficulties to efficient and cost-effective mining. Development and testing of methodologies to predict dyke behaviour and mitigate problems encountered during mining.
