Field Research

In the Lantagne Group, we conduct laboratory, field, and policy implementation-based research to reduce the burden of infectious diseases. While interventions can be designed in the laboratory, oftentimes the most valuable lessons for product design, user interface, and effective use come from working directly with the intended users and beneficiaries and understanding how they interface with the intervention. Our group conducts a variety of field studies, including technical assistance and evaluation projects across countries, retrospective evaluations, and assessment of effectiveness and appropriateness of products. Our group has developed a methodology to assess both the effectiveness at improving water quality and the appropriateness with the intended users of interventions; starting with a baseline survey, continuing with distribution, and then follow-up at 1, 3, 6, and 12 months after distribution.
