At the National Perinatal Epidemiology and Statistics Unit of the Centre for Big Data Research in Health, I am leading and collaborating a number of project using large-scale data linkage with multiple researchers and partners on examining effectiveness and safety of smoking cessation pharmacotherapy; accuracy and effectiveness of international growth charts on measuring small and large for gestational age newborns; impacts of maternal country of births on adverse perinatal outcomes; and effectiveness and safety of medically assisted reproduction treatment on mothers and babies.    

My Teaching

I am currently teaching Epidemiology and Biostatistics to health care professionals at the School of Women's and Children's Health.
