Epidemiologist & Maternal & Child Health Specialist
About Angelica Diaz
In 2021, Angelica Diaz led a rapid-response field study across rural Guatemala that linked seasonal dengue surges to altered placental cytokine profiles in third-trimester pregnancies, evidence later cited in WHO’s updated antenatal surveillance guidelines. She doesn’t treat disease in isolation; she maps how pathogens reshape developmental trajectories before birth and through early childhood, using spatial epidemiology layered with longitudinal biomarker data from cord blood banks and community health worker logs. Her lab pioneered the 'Maternal Infection Timing Index', a validated tool that stratifies neonatal sepsis risk not by pathogen type alone, but by gestational week of maternal seroconversion. Trained in both molecular virology and participatory action research, she co-designs diagnostic protocols with Indigenous midwives in Oaxaca and publishes bilingual clinical decision aids for low-resource clinics. Her work resists silos: she sees Zika not as a neurodevelopmental threat alone, but as a lens into how systemic gaps in water infrastructure, gendered care labor, and vaccine hesitancy converge at the bedside.
