Nina Sophia Link is a postdoctoral researcher specialising in public health and the micro-foundations of child undernutrition in India. Her research combines intuitive and culturally adapted smartphone surveys with image-based machine learning and computer vision techniques to advance community-led monitoring of child nutrition and support evidence-based decision-making in times of crisis. She completed her PhD at the Geneva Graduate Institute, where she examined the social and behavioural roots of child undernutrition in Kenya. Currently, she works on the SNSF- and Innosuisse-funded Artificial Intelligence for Monitoring Malnutrition (AIMM) project, developing and testing an AI-enhanced smartphone application for accurate, timely, and non-intrusive nutrition monitoring in low-resource settings.
