How can you make a difference?  

Traditional health messaging often fails to resonate with adolescent communities, particularly around sensitive topics like HPV vaccination where cultural beliefs, peer influence, and misinformation shape decisions more powerfully than expert recommendations. Recent breakthrough research from the Mercury Project's multi-country study "Developing a Scalable Community-Driven Approach to Combatting Health Misinformation" has demonstrated that when communities create their own health messages, these crowd-sourced communications significantly outperform standard expert designed campaigns. The approach works because it harnesses authentic language, cultural references, and persuasive strategies that naturally emerge from within communities, the same peer-to-peer channels through which both accurate information and misinformation already spread. The consultant will support the data science components of a project that establishes a systematic, evidence-based methodology for developing and testing crowd-sourced peer-to-peer messaging to increase HPV vaccination uptake among adolescents in Uganda and Kenya. Building on the Mercury Project's successful demonstration that community crafted messaging can increase vaccine impact by up to 50% compared to standard government messages, the consultant will test in both online and offline settings whether authentic peer voices can overcome the cultural barriers and trust deficits that limit current HPV vaccine coverage, which remains as low as 35% in some countries. This project evaluates whether crowd-sourced, community-generated messaging can outperform traditional expert designed communication in increasing HPV vaccination uptake among adolescents. The study integrates community message generation, AI-powered thematic clustering and message refinement, crowd forecasting, and cRCTs. The Data Science Consultant will play a central role in designing, implementing, and validating the data pipelines, NLP models, and experimental analytics that underpin this methodology. The consultant will lead the end-to-end data science workflow, including:

• Large-scale text data processing (11,000+ responses)

•Natural language processing and clustering

• LLM-assisted message generation

• Experimental design support and statistical analysis

• Integration of behavioral and administrative datasets
