Research

My research focuses on dissecting ore deposit systems through the application of bulk geochemical and advanced micro-analytical techniques. Much of this research has centred on the mineralogy and residence of precious metals and energy critical elements in sulphide and gangue minerals from ore deposits as well as waste tailings. The growing need for these elements in technological and green energy applications makes the characterisation of both existing reserves and prospective regions for exploration critical to addressing current supply restrictions and future demand. I continue to actively research the petrogenesis of REE and critical trace elements in hydrothermal exhalative systems and have also initiated several research streams investigating geochemical variations in carbonate hosted Zn-Pb deposits of the Irish Midlands, Devonian granite-hosted Sn-W-Mo-Cu deposits and a wide range of epigenetic Au, Ag, and base-metal systems.

Trinity College Dublin, mining and exploration companies active in Ireland (Teck Resources, Boliden, Lisheen Mine, Connemara Mining and Lundin Mining), as well as Geology alumni have joined forces to establish this sponsored position in Economic Geology.

Projects

I currently supervise 3 postgraduate students on geochemistry projects in the Irish Midlands as they pertain to the carbonate-hosted Pb-Zn deposits. Students will elucidate isotopic and trace-element systematics within bedrock, till, soils, peat and vegetation surrounding areas of known mineralization in the development of geochemical vectors for exploration; projects are supported by the IRC and EU (Marie Currie - IsoNose framework) as well as Industry sponsors TECK and Boliden. I am currently looking for students interested in postgraduate research opportunities on epithermal base-metal (Glendalough), granite-hosted Sn-W-Mo, and Pb-Zn deposits within Ireland and around the world.
