Braulio Mark Valencia Arroyo, MD, MSc, PhD, is a clinician–scientist and early-career researcher at the International Centre for Future Health Systems, University of New South Wales (91ɫ��Ƭ), Sydney. His expertise lies at the intersection of molecular diagnostics, infectious diseases, and translational research, with a strong focus on developing and applying disease biomarkers. His work spans the design and evaluation of observational and interventional studies, as well as the development of molecular assays for pathogen detection, particularly in neglected tropical diseases. He also investigates host genomic determinants of severity and susceptibility in acute and chronic infections. Dr Valencia Arroyo’s dual clinical and laboratory background has enabled him to contribute to high-impact systematic reviews and meta-analyses aimed at improving access to diagnostics and care pathways for viral and parasitic infections. His research is grounded in multidisciplinary collaborations across global health settings and reflects a consistent effort to integrate laboratory science with clinical and epidemiological insights. Driven by a commitment to equity, his clinical practice, teaching, and research are shaped by diverse global health experiences and a strong advocacy for priority populations. He is a passionate proponent of precision medicine, particularly its application to prevent and enable early, effective interventions for complex traits. His long-term vision is to ensure equitable access to personalised healthcare by translating cutting-edge multi-omics technologies into real-world primary care.
