Demos.Science is an initiative of researchers based at the Mahidol-Oxford Tropical Medicine Research Unit (MORU) in Bangkok, Thailand. Established in 2020, Demos.science seeks to create a collaborative platform to support and facilitate crowd-sourced randomized trial based research on questions of everyday concern to the public. Demos also serves as an experiential learning environment where users can learn about randomized trials -- why they can provide high quality answers to many research questions, and how they are run.
