About the Author
Roberto Romero-Gonzalez received his PhD in Chemistry in 2002 from the University of Granada, Spain. After two years postdoctoral work at the University of Lund, Sweden, he joined the research group "Analytical Chemistry of Contaminants" (University of Almeria, Spain). Since December 2008, he has obtained several contracts (i. e. Ramon y Cajal Program) as senior researcher at the University of Almeria. He is the co-author of more than 90 research papers published in international journals related to the determination of bioactive compounds, contaminants, and organic residues in environmental and food matrices, applying chromatographic techniques coupled to mass spectrometry analysers (high and low resolution). Antonia Garrido Frenich is full professor of Analytical Chemistry at the University of Almeria, Spain. She heads the research group "Analytical Chemistry of Contaminants," where her research is focused on developing analytical methods for the simultaneous determination of different classes of residues and organic contaminants in environmental, biological, and food matrices, based on the application of chromatographic techniques coupled to low and high resolution mass analysers. She is author or co-author of more than 240 research papers and book chapters related to these topics.
