About  |  Publications 


Dr. Wen Zou received her Bachelor's of Science in microbiology and Master's of Science in molecular microbiology from Shandong University, China. Dr. Zou received her Ph.D. in biochemistry and molecular microbiology from Kyoto University in Japan, after a two year postdoctoral experience at McGill University in Montreal, Canada. She joined NCTR in 2006 as a postdoctoral fellow in the Division of Microbiology. Dr. Zou was appointed as a visiting scientist in 2009 in the Division of Bioinformatics and Biostatistics (previously the Division of Personalized Nutrition and Medicine). She has received several awards for her work at FDA, including the “NCTR Director’s Award,” and “NCTR Outstanding Service Award.”

Research Interests

Dr. Zou's research expertise in broad scientific areas include microbiology, molecular biology, food safety, bioinformatics, statistics, text mining, and data mining. Her primary research is in the areas of:

  • Microbial next-generation sequencing data analysis and data mining
  • Safety-signal detection from FDA Spontaneous Reporting Systems (SRSs) and Electronic Health Records
  • Big-data analysis and visualization on knowledge discovering and safety-signal detection

Dr. Zou has been a Principal Investigator (PI), Co-PI, or participating scientist in more than ten research projects at NCTR and with other FDA Centers. Currently, she is the PI for two projects:

  • Developing a novel data-mining and data-visualization method for safety surveillance of the FDA adverse event reporting systems
  • Bioinformatics methodology development for microbial next-generation sequencing data analysis and data mining
