Anastasia Chrysovalantou Chatziioannou is a Scientist specializing in metabolomics and analytical chemistry at the Nutrition and Metabolism Branch of the International Agency for Research on Cancer (IARC). Her work focuses on developing advanced analytical techniques for clinical biomarker identification, particularly in neonatal conditions like necrotizing enterocolitis and sepsis. She holds a PhD in Analytical Chemistry from Aristotle University of Thessaloniki (2019), an MSc in Chemical Analysis from National & Kapodistrian University of Athens (2014), and a BSc in Chemistry from Aristotle University (2011). Her research interests emphasize metabolic profiling optimization, proteomics applications in neonatal critical care, and biomarker validation through mass spectrometry. She contributes to international scientific communities via membership in the Metabolomics Society and the Association of Greek Chemists. Key research trends in her publications include applying GC-MS and LC-MS/MS technologies to clinical samples, optimizing sample preparation protocols, and identifying metabolomic signatures for disease diagnosis. Her work bridges analytical chemistry innovations with clinical applications in neonatal and infectious disease contexts.
