My research is focusing on the functional role of trace elements in plants, including physiological and biochemical studies of manganese (Mn), zinc (Mn), iron (Fe) and copper (Cu) in plants. In the research group we have developed an advances and diverse ICP-MS based technolgy platform to study the chemical speciation of trace elements in plant tissue, with a special focus on linking chemical speciation with human bioavailability of Fe and Zn in plant based foods. Recently, we have initiated work on food authentication, where we develop multi-elemental and isotopic fingerprinting tools to determine the geographical origin and agricultural mangement form used during plant cultivation.
