I joined the School in December 2020 and currently work with Professor Mark Jit and Dr Kaja Abbas on measles vaccine modelling in low- and middle-income settings. Prior to this, I focused on the epidemiology and control strategies of tuberculosis (TB), both in Taiwan and at the global level, at Imperial College London. I also participated research on coronavirus disease 2019, in particular estimating the excess TB burden relating to health service disruption during a lockdown.
