Dr. Xianhong Xie, Ph.D.

Xianhong Xie, Ph.D.

Research Assistant Professor, Department of Epidemiology & Population Health

Areas of Research: Biostatistics, Epidemiology methods, Longitudinal data analysis, Missing data

Professional Interests

Dr. Xie’s research focuses on developing statistical methods for modeling missing data due to detection limits in longitudinal study. He also works on generalized linear mixed models with measurement errors and detection limits, both of which are common in lab assays. His other research interests include genomic data analysis, epidemiological methods, survival analysis, and statistical computing.

He has been working on data analysis on HIV and HPV in a large longitudinal cohort: the Women’s Interagency HIV Study (WIHS). He is also the lead biostatistician in analyzing the patients on placebo in a lupus study, a disease that affects millions of people worldwide and is very heterogeneous.
