Research Interests and Key Publications:
Dr. Ramachandran Thiruvengadam’s research focuses on reducing adverse pregnancy outcomes through public health interventions. He, as a member of the interdisciplinary Group for Advanced Research on Birth Outcomes – DBT India Initiative (GARBHINI) program, leads clinical and epidemiological studies to identify multidimensional risk factors for preterm birth and fetal growth restriction. His work combines classical epidemiology with modern data science, developing population-specific models and tools driven by artificial intelligence and machine learning. He also explores the impact of environmental factors on pregnancy. Dr. Thiruvengadam has contributed significantly to clinical and translational immunology, especially in understanding COVID-19's implications on pregnancy and vaccine effectiveness.
