Research interests

I am a biogeochemist who studies the cycling of 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 trace element resources for primary production and carbon burial in the ocean (e.g. iron), and 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 of iron and many other redox-sensitive trace elements and isotopes (TEIs) in the ocean and sediments, separating aqueous, solid and colloidal phases, and measuring these by Inductively Coupled Plasma-Mass Spectrometry. I also look for the mechanisms controlling TEI distributions and evaluate their importance in nature using micro-cosm experiments and theoretical toolkits (e.g. Isotope mass-balance, 1-D steady-state, and 3-D atmospherically-coupled ocean box models).

All of my research is collaborative. Most seeks simply to understand how the ocean sustains life and shapes the habitability of Earth’s surface envionrment, while some also informs national and international governance of the shelf-seas and deep-ocean environment.

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

(1) Understanding controls of the global carbon cycle

(2) Developing TEI tracers of the environment

(3) Evaluating impacts of human activity

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.
