I am primarily interested in the statistical analysis of repeated measurements of biomarkers with time-to-event data. Examples include among others: CD4 cell counts for HIV infected patients, PSA levels for prostate cancer patients, and serum bilirubin levels for liver cirrhosis patients.

My focus is in studying the association between such markers and the risk for an event, and developing dynamic prediction tools. Positions and employment: - Associate Professor, March - present, Dept. Books: Rizopoulos, D. Journal of Statistical Software, to appear.

Prof.dr. D. (Dimitris) Rizopoulos

I am a professor of biostatistics at the Erasmus Medical Center Rotterdam. My research focuses on joint models for longitudinal and time-to-event data with applications in biomarker identification, precision medicine, screening and active surveilance. I currently serve as a co-Editor for Biostatistics [ twitter handle ]. Novel methods for optimally planning when to collect longitudinal measurements or event information.
