Barbas is known for her research on metabolomics, a field she was first introduced to while she was a Marie Curie fellow.[4] Her early research centered on the analysis of vitamins[5][6] and development of chemical methods to analyze compounds such as caffeine.[7][8] Her subsequent research has developed methods to analyze organic compounds in pharmaceutical drugs[9] and foods,[10][11] and defined biomarkers for diseases such as leukemia[12] and Parkinson's disease.[13] She is also known for defining quality assurance protocols for metabolomics data analysis[14] and establishing workflows to analyze metabolomics data.[15]
