Research & Publications
Dr. Thio has two primary research interests. The first is HIV-HBV co-infection, where she has projects in Nigeria, Australia and the United States. In addition, she is leading a multicenter international study looking at HIV-HBV co-infection within the ACTG framework.
Her second area is on the human genetic determinants of HBV and HCV clearance, where she examines polymorphisms in human genes in persons that have either recovered from or have a persistent viral hepatitis infection.
