Research interests

Development of dynamic statistical models to describe, explain and predict chronic disease progressions. I specialized in the joint analysis of correlated longitudinal markers and event time history using the so called joint models with applications mainly in neurodegenerative diseases (e.g., Alzheimer’s disease) and cancers. My works often involve latent processes to translate dynamic health phenomena measured by repeated markers, and latent classes to translate the heterogeneity of disease progression. I have also worked on the development of individual dynamic predictions that quantify the risk of experiencing a clinical event based on the dynamic history of an individual. All my works are motivated by epidemiological and clinical questions thanks to strong collaborations with epidemiologists and clinicians, and access to large cohort studies. My developments are made available in R packages with constant maintainance and upgrades.

I serve as Associate Editor for Biometrics (since 2014) and Biostatistics (since 2016).

I belong to the international initiative in Methods in Longitudinal Research in Dementia (MELODEM).
