Postgraduate Research Opportunities
I don't have any funded PhD or MSc by Research projects available at the moment but I am always happy to hear from prospective students who wish to undertake an MSc by Research or PhD in my fields of interest (see below).
My main research interest revolves around carbon and carbonates. I use a range of analytical methods, from X-Ray Computed Tomography (XCT) to novel isotope geochemistry techniques such as clumped isotopes, to address a range of research questions:
- atmospheric CO2 capture with slag and rocks
- pollution from legacy industrial wastes
- carbonate mineralisation in hydrothermal fluid flow and geothermal energy systems
- carbonate hydrocarbon reservoir diagenesis
I have a particular interest in legacy industrial waste products, particularly the breakdown of iron and steel slags, both from their potential for capturing atmospheric CO2 as well as the challenges they pose with pollution.
Additionally, I retain an interest in Precambrian gneiss complexes which I studied during my PhD, ranging from mineral deposit formation to zircon geochemistry.
