Description of Research Expertise
I study the relationship between immunosuppression strategy and outcomes after liver transplantation. I have previous expertise in research related to organ allocation, living donor liver transplantation, the effects of transplant policy-making, disparities in liver care and center variability in patient care. These efforts have spanned adult and pediatric transplant populations. I also have research interests in autoimmune hepatitis and alcohol-associated liver disease. I have an advanced degree in clinical epidemiology, and have expertise with observational study designs, large databases and statistics.
