I am an infectious disease modeller at LSHTM. I received my PhD in Public Health from the Saw Swee Hock School of Public Health (SSHSPH) at the National University of Singapore (NUS), where I have a secondary appointment. From 2019 to 2021, I chaired the seminars at the Centre for the Mathematical Modelling of Infectious Diseases (CMMID) at LSHTM.

With Professor Mark Jit, I helped design and coordinate Health Decision Science, a recommended course for MSc Public Health (Health Economics and Health Services and Management) and MSc Health Policy Planning & Finance. I also lecture on the Public Health and Epidemiology module, a core module for the undergraduate Public Health major at NUS. I have conducted several courses: I have lectured at and facilitated data analysis and biostatistics R workshops — at the University of Public Health (Yangon, Myanmar), Mahidol University (Bangkok, Thailand), UCSI University (Kuala Lumpur, Malaysia) — and infectious disease modelling workshops — at LSHTM, NUS and Ministry of Health (Brunei). I facilitated a Health Technology Assessment workshop for health professionals jointly organised by the NUS and the Health Intervention and Technology Assessment Program (HITAP). I also lead the Mathematics and Public Health course with secondary school students in Singapore. 


I supervise undergraduate and postgraduate students at LSHTM and NUS.


As an infectious disease modeller, my research interests involve building computational models to understand the population impact and cost-effectiveness of interventions against infectious diseases. I led the development and updates of the global age- and location-specific contact synthetic contact matrices for contact-transmissible infections. I am also involved in several modelling studies to evaluate the cost-effectiveness and feasibility of the global eradication of vaccine-type human papillomavirus. I provide technical expertise to the national Tuberculosis and HIV programmes and other local partners in Cambodia, where we evaluate active case-finding modalities and interventions to improve treatment outcomes.
In my secondary appointment at NUS, I lead the NUS public health research office in Lao PDR, where we collaborate with Lao Tropical & Public Health Institute and the University of Health Sciences of Lao PDR.
