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 maintain an honorary position as a research fellow. Since September 2019, I chair the seminars at the Centre for the Mathematical Modelling of Infectious Diseases (CMMID) at LSHTM.

Together with Professor Mark Jit, I helped design, 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 Machine Learning module, which is part of the new MSc in Health Data Science. In addition to the LSHTM courses I have been involved with, as part of outreach and regional engagement, I have conducted several training courses over the last five years: I have lectured and facilitated for several data analysis and biostatistics R workshops at University of Public Health (Yangon, Myanmar), Mahidol University (Bangkok, Thailand), UCSI University (Kuala Lumpur, Malaysia). I have also facilitated a Health Technology Assessment workshop for health professionals jointly organised by the National University of Singapore and the Health Intervention and Technology Assessment Program (HITAP). I was invited to speak at the Option X Pre-conference workshop: Introduction to Infectious Disease Modelling, held at the National University of Singapore.


I collaborate closely with the national tuberculosis programme in Cambodia Ministry of Health and WHO to build computational models for infectious diseases and conduct cost-effectiveness and feasibility studies.
In my role at LSHTM, I am currently evaluating the cost-effectiveness and feasibility of a global eradication of vaccine-type human papillomavirus.
Together with the national tuberculosis programme in Cambodia and WHO Western Pacific Region office, I am conducting a holistic overview of the TB care and services in Cambodia, which involves developing a monitoring tool to inform the way towards ending TB in Cambodia. We are also evaluating several TB active case finding modalities in Cambodia.
