Biosketch

Dr. James Ahodantin grew up in France and received a training in Infectious diseases and Vaccines followed by a Ph.D. degree in Virology and Immunology at Sorbonne University in Paris where he discovered that hepatitis B virus X protein (HBx) promotes the development of hepatocellular carcinoma through the dysruption of liver polyploidization. Dr. Ahodantin has also significantly contributed to the development of humanized mouse model for HBV study. Next, he completed his postdoctoral training at University of North Carolina Chapel Hill in Prof. Lishan Su's lab where his research focused on the investigation of mechanisms of HIV and HBV immunopathology in the liver. Through over several years of work, training, and teaching/mentoring, Dr. Ahodantin have developed extensive expertise in Virology, Immunology and Liver Biology.

Research Interests

Dr. James Ahodantin current research focuses on HBV and HIV infections/co-infection, and related liver diseases using mouse model. Co-infection with HBV and HIV-1 is common, and HIV co-infection can exacerbate the progression of viral hepatitis and accelerate liver disease progression. Thus, understanding how both viruses interact, and the impact on the host immune system and liver is crucial. His research focuses on deciphering and targeting key factors favoring viral immune escape leading to chronic inflammation and disease, and ultimately to developing the next generation of clinical interventions.
