About

Professor Auxiliar Alexandra Guedes is a faculty member at Universidade do Porto Faculdade de Ciências in Portugal. Her research primarily focuses on the magnetic properties of iron ores, fluid inclusion evidence of deep-sourced volatiles, and the geogenic characterization of airborne particles. Additionally, she explores topics related to municipal solid waste incineration ash and the influence of photoselective nets on pollen traits.
