Dr. Junfeng Wang got his Bachelor in Statistics from Renmin University of China, M.S. in Quantitative Finance and Actuarial Science from Tilburg University, and Ph.D. in Biostatistics from University of Amsterdam. His Ph.D. thesis focused on the statistical methods in evaluating diagnostic tests and biomarkers, in both primary studies and systematic reviews.

His current research focuses on the following main areas: (1) statistical methods in (comparative/net-work) meta-analysis of diagnostic test accuracy; (2) advanced statistical methods in survival analysis; (3) development and validation of clinical prediction models; (4) complicate data analysis in observational research.

Specifically, at European Society for Blood and Marrow Transplantation(EBMT), he actively collaborates with physicians in the field of stem cell transplantation from different countries in Europe. He leads statistical analyses for multiple EBMT studies, from study design, performing the statistical analysis to writing the manuscript.

Meanwhile, he is working on methodological researches in LUMC, including imputation of missing values for survival data, variable selection after imputation in prediction model development, evaluation of model performance with imputed data.

In diagnosis and prognosis, he is interested in the receiver operating characteristic (ROC) analysis and its extension to survival data, evaluating repeated measurements/longitudinal marker, and clinical prediction models.
