I am a Postdoctoral Fellow in Department of Nutrition at Harvard T.H. Chan School of Public Health (Supervisor: Professor Jorge Chavarro). I was a Postdoctoral Fellow in National Institute of Environmental Health Sciences at National Health Research Institutes, Taiwan. I graduated from National Taiwan Normal University with a bachelor degree in health education. When I was pursuing a master’s degree at National Taiwan University, I decided to transfer to the direct Ph.D. program and earned my doctoral degree in Environmental Epidemiology (Supervisor: Professor Yue-Liang Leon Guo and Professor Pau-Chung Chen ) and also completed the certificate program in Biotechnology in June 2015. During my Ph.D. studies, I advocated policy changes in regard to the health care for the victims in Yucheng who suffered from the accident happened in 1979 in Taiwan. More than 2,000 people were exposed to high concentration of polychlorinated biphenyls (PCBs) and dibenzofurans (PCDFs). I realized the important role of public policy in shaping the public health care, and thus I decided to pursue an LL.M. degree in National Chengchi University, and I got my LL.M. degree (Supervisor: Professor Hung-En Liu) in July 2015. My master’s thesis focused on disclosure of conflict of interest (COI) of biomedical researchers.

I have experience in conducting the epidemiological study, field study, and performing statistical analysis. During my Ph.D. studies, I studied the health effects after exposure to PCBs and PCDFs. In 1979, there was an outbreak of severe acne, skin pigmentation, and conjunctivitis in central Taiwan. Most of the cases had consumed the same brand of cooking oil that was bought at the same store. The illness, and its relation to cooking oil consumption, resembled a form of PCBs and PCDFs poisoning (called “Yusho,” oil disease in Japanese) that had occurred in western Japan in 1968, and oil and blood samples sent to Tokyo for analysis had high concentrations of PCBs and PCDFs. Yucheng (“oil disease” in Chinese) thus became the second recorded disease outbreak due to rice bran cooking oil contaminated by PCBs/PCDFs during manufacture. Although about 2,000 persons registered with health agencies as being exposed after each episode, the exact number of victims was unknown. I followed the exposed persons and compared their cause-specific mortality with that of neighborhood referents 30 years after the accident. Furthermore, I collaborated with Japanese researchers conducting a meta-analysis of Yucheng and Yusho cohorts to re-evaluate the effects of PCBs and PCDFs on major causes of mortalities. PCBs have been suggested as neurotoxicants especially when exposed during prenatal and early postnatal periods, and known to cause neurological effects including auditory impairments. I therefore conducted a follow-up study to examine the association between gestational PCBs/PCDFs exposure and auditory function in Yucheng children’s early adulthood.

Currently, I am studying how environmental pollutants and nutritional factors affect reproductive health.
