Peter Bacchetti, PhD
Research Interests
I am currently working on new methods for modeling biopsy-measured fibrosis progression. I also contribute to a variety of liver-related research projects in my role as collaborator and director of the CTSI’s Biostatistical Unit. Current work for the Liver Center addresses how alcohol consumption influences progression of HCV, the impact of hepatitis viruses in HIV-infected patients, and the influence of HCV on glucose metabolism. My activities on these studies include advising on data collection instruments and procedures, meeting with investigators to clarify goals, developing and implementing analysis plans, interpreting results, and contributing to original publications. Many of these collaborations require innovative use of modem statistical methods, such as mixed effects models with multiple random effects and use of bootstrapping to obtain valid confidence intervals and p-values when assumptions for standard methods are not met.
