My research focuses on trace metals biogeochemistry with particular reference to barium. I am interested in the chemical, biological and physical processes which affect trace element distributions and behaviour in both coastal and open ocean regimes. This research combines dissolved and particulate Ba and barite studies and analytical chemistry, and is approached from two directions: field measurements and laboratory studies, with projects ranging from developing analytical method for elements determinations to studies on barium dynamics in various systems (Austral, Mediterranean, Arctic). The Ba proxy is used as a tracer of particulate organic carbon remineralization at mesopelagic dephts.The laboratory utilizes high resolution inductively coupled plasma mass spectrometry and voltammetric techniques to investigate the distribution and chemical speciation of trace elements in seawater.
