    Research Interests

    My main research programme is to identify effective strategies to modify risk factors (nutritional, environmental and genetic) during pregnancy on adverse maternal and their offspring outcomes in longitudinal prospective cohort studies; evaluate interventions in perinatal care through randomized controlled clinical trials; and to provide evidence-based interventions to reduce the incidence of adverse perinatal outcomes and to improve maternal and their children health in long-term.

    • Risk factors (nutritional, environmental and genetic) during pregnancy on maternal and infant outcomes
    • Biological mechanisms underlying vitamin D during pregnancy and perinatal outcomes
    • Evaluation of perinatal care through randomized controlled trials
    • Longitudinal cohort studies on maternal and offspring long-term follow-up
