I graduated in medicine from Kaohsiung Medical College in Taiwan, studied environmental and occupational medicine in the Institute of Public Health at the National Taiwan University College of Medicine, and got MSc and PhD degrees in Epidemiology and Population Health at the London School of Hygiene and Tropical Medicine in United Kingdom.
I have been working at the Institute of Occupational Medicine and Industrial Hygiene of National Taiwan University College of Public Health since February 1996 and have been appointed as the director since August 2014. Currently I am a 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 have also been appointed as the director of the Department of Environmental and Occupational Medicine at the National Taiwan University Hospital and National Taiwan University College of Medicine since 2012.
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 289 scientific articles and received the Distinguished Research Award from the Ministry of Science and Technology in Taiwan. I have served as chair of the Scientific Committee on Reproductive Hazards in the Workplace (RHICOH), International Commission on Occupational Health (ICOH) since 2012, and was the first chair of the Birth Cohort Consortium of Asia (BiCCA) in 2012-2014.
