Research Interests

Dr. Chen’s research lands on both novel statistical research and impactful biomedical research. Currently, her statistical research focuses on missing data, survival analysis (especially time-varying effect and treatment switching), Bayesian methods in big data, and penalized approach for 1<n/p<10. She also devotes to develop statistical method in using electronic health records (EHRs) and genetics information in precision medicine. Her other significant biomedical research areas include cancer, ophthalmology, infection disease, cardiovascular diseases, and suicide.
  • Statistical Analysis with Missing Data
  • Survival Data Analysis
  • Electronic Medical Record
  • Treatment switching/Noncompliance
  • Bayesian Statistics
  • Semiparametric/Nonparametric Method, Robust Analysis
