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, precision screening and active surveillance. I currently serve as a co-Editor for Biostatistics [twitter handle].

Extensions of joint models for improving subject-specific predictions.
Computational methods for multivariate joint models.
Novel methods for optimally planning when to collect longitudinal measurements or event information.
The current composition of my research group:
Pedro Manuel Miranda Afonso: Pedro works on extensions of joint models for recurrent event data and spatial correlations with applications in cystic fibrosis.
Arnau Garcia Fernandez: Arnau works in combinations of joint models and machine learning.
Nina van Gerwen: Nina works in causal dynamic predictions using joint models and machine learning.
Aglina Lika: Aglina works in developing methodology and software for Bayesian multivariate mixed effects models.
Fridtjof Petersen: Fridtjof works in extending joint models to the setting of intensive longitudinal data.
Zhenwei Yang: Zhenwei works on applications of joint models in personalized scheduling with applications in prostate cancer research.
