Research interests

I am an ocean scientist and geochemist who studies the reactions and transport chemical elements between the land, ocean and seafloor to learn how these impact marine life and Earth's surface environment over time. I am interested in the elements that either drive or repond to changes in the global carbon cycle, and seek to learn how exchanges between crustal rocks, seawater and sediments can impact marine food webs and Earth’s atmospheric oxygen and greenhouse gas compositions.

I specialise in the collection low abdundance and redox-sensitive ‘trace’ elements and isotopes in the ocean and sediments – separating aqueous, solid and colloidal phases – and measuring these by Inductively Coupled Plasma-Mass Spectrometry. I look for the mechanisms controlling oceanic element and isotope distributions and evaluate their importance in nature using micro-cosm experiments and theoretical toolkits (e.g. Isotope mass-balance, and reaction-transport models at varied scales and resolution).

Research activities fit into one or more of the following three themes: 

(1) Understanding controls of the global carbon cycle

(2) Developing element and isotope tracers of the ocean environment

(3) Evaluating impacts of human activity on element cycles in the oceans

I am always interested to hear from aspiring Ph.D. or postdoctoral candidates. If this is you, feel free to contact me directly with project related enquires.
