Research Interests

Chen has extensive experiences in big data. She has outstanding skills in computer programming, scientific research and statistical analysis. Chen is the leader of managing several large national databases, including private health insurance claims data, Medicare data, and SEER data.

Chen’s current research is to expand the understanding of safety profiles of antidiabetic agents, improve available evidence used by the FDA for diabetes drug regulation, and help physicians identify the best treatment options. Her primary research interests include pharmacoepidemiology and pharmacoeconomics, particularly related to adverse cardiovascular, pancreatic, and cancer events associated with diabetes polytherapy using national administrative databases. Chen is also actively involved in research of other clinical outcomes in diabetic populations.

In addition to research, Chen is an integral member of the SLUCOR consulting practice. She provides analytic support for many grants and research projects for clients in academia, industry, government, and non-profit organizations. Through her consulting engagements, she has analyzed hundreds of datasets ranging in size and complexity from publicly available datasets to large administrative databases such as the private insurance claims databases (with 10-plus million unique patients). Before joining SLUCOR, Chen worked as a statistical consultant at Washington University School of Medicine assisting with various clinical studies in cardiology, pediatrics, orthopedics, and gastroenterology.
