He is particularly interested in leveraging causal inference methods to better design and analyze pragmatic and cluster-randomized trials. His work in clinical trials methodology also focuses on informative dropout, clustered survival methods, estimand refinement, and Bayesian trial applications. He also leads and collaborates on multiple studies focused on the allocation of solid organs for transplantation and on long-term outcomes following hospitalization. He is the author of more than 180 scientific publications and is involved in several international research activities, including randomized trial data safety and monitoring boards, societal and trial steering committees, and research consortiums. He also serves as a statistical editor to several leading journals in critical care medicine and is an editor of the International Journal of Epidemiology.
