Senior Scientist - Gastroenterology (Hepatology) Washington University in St LouisSenior Scientist - Gastroenterology (Hepatology)WashingtonWe were among the first groups to establish hepatitis B and hepatitis C virus infection models using stem cell-derived hepatocytes, and we have continued to combine these systems with primary human hepatocytes, CRISPR/Cas9 gene editing, and genetically distinct HBV clones to dissect the host and viral factors that determine infection and persistence. Our long-term goal is to understand the complex interactions between HBV and its host that drive viral persistence and to use these insights to identify new strategies toward a functional cure for chronic hepatitis B, which remains a major global health challenge and an important cause of liver related morbidity and mortality.
