Postdoctoral Research Associate(s)

Jiawen Liao is the post-doctoral fellow working in Dr. Zhanghua Chen research group, Keck School of Medicine of University of Southern California. He obtained PhD in Environmental Health Sciences at Emory University in 2020 with training in air pollution exposure assessment and environmental epidemiology. At USC, he will work on analyzing maternal and child health effects of air pollution exposure in related epidemiological studies. He will also apply various analytical tools to integrate ‘exposome’ with omics data, in order to understand environmental factors for complex diseases. 

Research Coordinator / Biostatistician(s)

Chenyu Qiu majored in Biostatistics and achieved master’s degree from University of Southern California in 2020. In the fall of 2019, Chenyu joined Dr. Zhanghua Chen’s team exploring the association of targeted metabolites and diet with obesity and insulin resistance in young adults. At present, she is a senior research coordinator continuing to investigate the association of air pollutants with metabolomic features, and the effects of metabolomic features on altering newborn’s birth weight.
