Lorenzo Trippa

Assistant Professor of Biostatistics

Department of Biostatistics


I am interested in the development of adaptive clinical trial designs. My research includes the study of algorithms and methodologies for the analysis of data generated by adaptive trials. I am also particularly interested in Bayesian nonparametrics, a great source of modeling opportunity in biomedical applications as well as, both computational and theoretical problems.
