Dr. Nourhen Omri is a dedicated researcher in analytical and environmental chemistry, specializing in advanced inorganic, isotopic, and solid-phase speciation techniques for geochemical monitoring of trace elements and rare earths in complex environmental matrices. Her work focuses on understanding the behavior, distribution, and environmental impact of critical metals originating from phosphate-rich regions and their transfer into marine ecosystems, particularly within the context of industrial contamination. She possesses strong expertise in ultra-trace sample preparation, ion exchange chromatography, and contamination control under clean laboratory conditions, supported by proficiency in ICP-AES, ICP-MS, MC-ICP-MS, and XANES spectroscopy for elemental and isotopic characterization. Dr. Nourhen Omri has contributed to high-level research through collaborative projects involving multidisciplinary teams, international laboratories, and synchrotron-based analyses, strengthening her skills in method development, data interpretation, and geochemical modeling. Her scientific contributions include peer-reviewed publications addressing rare earth element behavior, digestion strategies for mineral and sediment matrices, isotopic tracing of metal pollution sources, and speciation studies of key contaminants in industrial by-products and marine sediments.
