Roberto Romero-González is Full Professor at the Department of Chemistry, University of Almería. He holds a PhD in Chemistry from the University of Granada (European PhD Mention, 2002), where he also completed his Bachelor’s degree. He held a Junta de Andalucía Predoctoral Fellowship and an MEC Postdoctoral Fellowship, conducting research at Lund University (Sweden). He later joined the University of Almería as a Juan de la Cierva and then Ramón y Cajal researcher. His teaching focuses on Analytical Chemistry, both in the Chemistry Degree and various Master’s programmes. His research centres on the analysis of bioactive compounds, organic contaminants, and residues such as pesticides, mycotoxins, and antibiotics in food, environmental, and biological matrices. He develops multi-residue methods using QuEChERS or dilute-and-shoot extractions, combined with LC–MS/MS and GC–MS/MS, as well as high-resolution mass spectrometry (Orbitrap). He also applies metabolomics and fingerprinting strategies based on mass spectrometry and NMR to characterize food quality and authenticity.
