She is also an Academy Fellow at the World Cancer Research Fund International, UK and an Ambassador at the World Cancer Research Fund, HK. Dr Kris Lok is a registered dietitian who has worked in academic institutions and hospitals both in Hong Kong and UK. Her current research interests include maternal and child health, specifically infant feeding. She has conducted a number of large randomized controlled trials of interventions to improve maternal and child health outcomes.


Maternal and Child health and nutrition, infant feeding, breastfeeding, human milk and gut microbiome, the Baby-Friendly Hospital Initiative, development and use of digital technologies in healthcare and healthcare education, and maternal and childhood vaccinations. Study methodologies involve large longitudinal cohort studies, population-based cross-sectional studies, and randomized controlled trials. My research goal aims to improve maternal and child health outcomes, inform public health policies and transform perinatal healthcare services.
