I have been working at the Institute of Environmental and Occupational Health Sciences (changed from Institute of Occupational Medicine and Industrial Hygiene) of National Taiwan University College of Public Health since February 1996. Currently, I am a distinguished professor and teaching children's health and the environment, women's health and the environment, developmental origins of health and disease, and statistics in environmental and occupational health. I served as director of the Department of Environmental and Occupational Medicine at the National Taiwan University Hospital and National Taiwan University College of Medicine in 2012-2018 as well as director of the Institute of Occupational Medicine and Industrial Hygiene at the National Taiwan University College of Public Health in 2014-2019.
Most of my studies are based on epidemiological methods and focus on occupational and environmental medicine, reproductive and developmental epidemiology, children's environmental health, and cancer chemoprevention. Also, I'm interested in maternal, reproductive and child health, and secondary data analysis. I have published more than 350 scientific articles and received the Outstanding Research Award from the Ministry of Science and Technology in Taiwan in 2015. I was the first chair of the Birth Cohort Consortium of Asia (BiCCA) in 2012-2014, and served as chair of the Scientific Committee on Reproductive Hazards in the Workplace (RHICOH), International Commission on Occupational Health (ICOH) in 2012-2018.
