I am Professor of Geology at the University of St Andrews, specialising in mineralogy, petrology and geochemistry, particularly in alkaline igneous systems. Much of my research has focussed on the petrology and petrogenesis of rare element deposits. Although I have worked on rocks all over the world, I have a particular reputation for fieldwork in the Arctic, notably Greenland.
I have consulted to several exploration companies over many decades and my geochemical work is underpinned by access to some of the best analytical facilities available worldwide.
I also talked about my research and my motivation to become a geologist to the GeoBUS outreach team in 2015.
