Co-founder, Nudge Thailand

Thailand

Panuwat Sajjaviriyakul is the co-founder of Nudge Thailand, which utilizes behavioral science to design public policies that improve environmental and social well-being. He implemented waste separation field experiments with the Bangkok Metropolitan Administration that reduced landfill costs by $4 million and lowered greenhouse gas emissions by 30,000 tons annually. Spurred by the structural inequalities he witnessed in remote regions, Panuwat believes that systems must be designed to make positive behaviors natural rather than relying on individual willpower. Panuwat transforms top-down governance into evidence-based models that prioritize human-centered insights over punitive measures. He blends engineering precision with psychological empathy to translate complex community data into scalable policies.
