Rui Miguel Pinheiro Vitorino is a Principal Investigator at the Department of Medical Sciences and the Institute of Biomedicine (iBiMED), University of Aveiro, Portugal. He holds a Ph.D. in Biochemistry and has extensive expertise in mass spectrometry-based proteomics, peptidomics, bioinformatics, and translational biomarker research. His work focuses on the molecular characterization of human disease, with particular emphasis on cardiovascular disease, cancer, stroke, obesity, and precision medicine. He has developed and applied integrative proteomic and multi-omic strategies to saliva, urine, plasma, dried blood spots, extracellular vesicles, and tissue samples, aiming to identify clinically relevant biomarkers and molecular signatures. His research increasingly integrates proteomics with bioinformatics, systems biology, and artificial intelligence to support disease stratification, biomarker validation, and clinical translation.
