Raul U. Hernandez-Ramirez

Raul U. Hernandez-Ramirez is a Research Scientist in Biostatistics at the Center for Methods in Implementation and Prevention Science (CMIPS) at the Yale School of Public Health. He serves as Director of the Dissemination and Implementation Science Methods (DISM) Core at the Center for Interdisciplinary Research on AIDS (CIRA) and is an Affiliated Faculty member at the Yale Institute for Global Health. His work bridges biostatistics, implementation science, and global health research with a focus on practical applications for public health improvement.

Dr. Hernandez-Ramirez earned his PhD in Public Health (Chronic Disease Epidemiology) from Yale University in 2018, following an MPhil in the same field in 2016. During his doctoral studies, he conducted research as a predoctoral visiting fellow at the National Cancer Institute (NCI). He further enhanced his expertise through specialized training programs including the Training Institute for Dissemination and Implementation Research in Cancer (TIDIRC) and the Multilevel Intervention Training Institute (MLTI) from NCI, as well as training in optimization of multicomponent interventions using the Multiphase Optimization Strategy (MOST).

His research primarily focuses on HIV/AIDS, cancer, and implementation science. He develops and applies causal inference methods for evaluating HIV prevention interventions and methods to account for exposure uncertainty in environmental health studies. His work spans multiple settings including New Haven, other locations in the United States, and low- and middle-income countries, particularly Mexico. He is particularly interested in adapting and developing interventions to increase the uptake of evidence-based practices for HIV and cancer prevention and care, including follow-up care for abnormal cervical cancer screens. He is a member of the Yale Cancer Center (YCC) and the Yale Institute for Global Health (YIGH).

Analysis of Dr. Hernandez-Ramirez's recent publications reveals a strong focus on gastric cancer epidemiology through the Stomach cancer Pooling (StoP) Project, examining dietary factors and their relationship to cancer risk. His work prominently features implementation science methodologies applied to HIV prevention and cancer screening programs, particularly in Mexican and other international settings. His research combines rigorous biostatistical methods with practical applications in global health contexts, with significant contributions to causal inference methods and network-randomized trial analysis.

• Provides expertise, consultations, and technical assistance on implementation science through CIRA's DISM core
• Contributes to projects in Ending the HIV Epidemic (EHE) priority areas through the CIRA-affiliated IS hub R3EDI
• Collaborates on research projects in New Haven, other US settings, and low- and middle-income countries including Mexico
• Offers seminars and trainings on research methods, design, and analysis to CIRA affiliates

Dr. Hernandez-Ramirez previously gained substantial research experience in nutrition, environmental health, and cancer at the National Institute of Public Health of Mexico, where he worked as a researcher and instructor and served as project coordinator, data manager, and main statistician for a multistate study. He holds an MSc in Epidemiology and a BSc in Nutrition, establishing a strong foundation for his current work at the intersection of nutritional epidemiology and implementation science.
