I am a physician, educated and trained in pediatrics and infectious diseases in Taiwan, and completed Epidemic Intelligence Service with the CDC Immunization Safety Office in the United States. I hold adjunct faculty appointments in the National Taiwan University Global Health Program and Children's Hospital.

In my previous role as Chief Medical Officer at Taiwan Centers for Disease Control, I worked in broad areas of infectious diseases, field epidemiology, surveillance, and social science, with a primary focus of research on applying real-world data to inform the use of vaccines. I played key roles in modernizing the vaccine safety infrastructure in Taiwan and am/have been actively involved in multi-country collaborative vaccine safety projects, both in resource-poor and -rich study settings.

Currently, I serve on the Coalition for Epidemic Preparedness Innovations funded Safety Platform for Emergency vACcines (SPEAC) (https://speacsafety.net/), guiding the operation of monitoring the progress and quality of work to ensure SPEAC standard and tools are valid and applicable across global settings. I also provide technical input to the CDC Global Immunization Safety Team in implementing/advancing vaccine safety responses in low- and middle-income countries, and to VAccine monitoring Collaboration for Europe (VAC4EU) (https://vac4eu.org/) on regulatory required studies on Covid-19 vaccine safety.
