I am a pharmacoepidemiologist using multinational electronic health records (EHRs) for causal inference research. I studied BSc Public health at the Chinese University of Hong Kong and a PhD in pharmacoepidemiology at the University of Hong Kong. I then moved to London to work at LSHTM in 2018. I have conducted epidemiological and pharmacoepidemiological research across diverse healthcare systems in UK, Hong Kong, Japan and Denmark. I am also a member of OpenSAFELY collaborative to work on COVID-19 research especially during early stage of pandemic. My research has been supported by several funding bodies including British Heart Foundation for investigating drug-interaction with direct oral anticaogulants, MRC grant and Hong Kong InnoHK grants, supporting the development and application of methodologies in EHR-based research. I'm currently the deputy director of the Centre for Global Chronic Conditions.

Teaching

I am a lecturer & course organiser of the Professional Certificate course in Pharmacoepidemiology and Pharmacovigilance and bespoke courses at LSHTM: https://www.lshtm.ac.uk/study/courses/short-courses/pharmacoepi-pharmac…

I am also a lecturer/tutor and supervise MSc students from the MSc in Epidemiology, MSc in Public Health and MSc in Health Data Science.

Research

My vision is to advocate the use of real-world evidence generation through applying novel methodologies in health data reserach. My work focuses on using methods such as self-controlled designs and propensity score to minimise confounding and bias, aiming to produce high-quality clinical evidence to inform prescribing decisions. My current research projects include drug-drug interactions and the safety profiles of cardiovascular and psychotropic medications. I am also using EHRs linked to meteorological data to investigate how heatwave alter medication effects.
