With a medical background and an MSc in Nutrition, I previously worked for the Determinants of Adolescent Social Well-being and Health (DASH) cohort study in the UK and the Born in Guangzhou Cohort Study (BIGCS) in China before my PhD studies. My previous research involves the association of nutrition/dietary behaviours with physical and mental health in adolescence and the perinatal period. My PhD research was to look at the causal effect of maternal vegetarian diet during pregnancy on offspring health by applying a range of causal inference techniques such as Mendelian Randomisation (MR), paternal negative control, within-sibling and cross-cohort comparisons, epigenome-wide association study (EWAS), and metabolome-wide association study (MWAS). I also worked on two mini-projects during my PhD - one investigating the impact of maternal coffee consumption on perinatal health and the other exploring potential drug targets for Alzheimer's disease. Now I am working as a postdoc Wellcome Trust Transition Fellow on pregnancy medication use and perinatal health, using national electronic health record (EHR) data from the UK and Sweden.
