Dr Patrizia Onnis is an internationally recognised researcher with more than 10 years of expertise in environmental mineralogy. She completed her Ph.D. at Liverpool John Moores University (LJMU), developing new research to investigate the behaviour of metals in mining-impacted catchments. Following research at the University of Exeter (UoE) focused on municipal and industrial wastes in coastal areas at the UK national scale. Coordination of sampling strategies, analysis, and delivery of management recommendations and scientific outputs were her core activities. Nowadays, she is employed as a researcher at the University of Cagliari (UNICA) developing innovative strategies for environment protection and valorization focusing on metal-rich materials. Research tools included novel approaches to characterise wastes and metal-impacted matrices in riverine and coastal environments. Dr Onnis undertook numerous fieldwork campaigns and laboratory accesses across the UK, EU, and the USA. Laboratory experiments included elemental and mineralogical characterisation of material via routine and cutting-edge instruments (ICP-MS, XRF, XRD, SEM, TEM, Zeta potential, polarography, chromatography, isotopic analysis, and synchrotron light lines). A strong international network is a legacy of her active multidisciplinary research in collaboration with government departments, scientific facilities, and academic partners. She secured funding and efficiently disseminated research outputs in peer-reviewed papers and conferences. For her merit, she received prizes at international conferences. Furthermore, Dr Onnis undertook lecturer and mentor tasks at UoE, LJMU, and UNICA. Dr Onnis possesses specialist knowledge and confidence in undertaking environmental mineralogy research as a principal investigator or collaborative researcher, ensuring meeting project milestones and efficiently disseminating scientific and management outputs among the scientific and stakeholder communities.
