Arnaud Carpentier is a Research Scientist at the Institute for Experimental Virology, TWINCORE, Center for Experimental and Clinical Infection Research, who works on the design of highly relevant in vitro models for different viral infection in hPSCs-derived cells. He received his Bachelor’s Degree in Biology from Faculté Libre de Science de Lille (FLS) and his Master’s degree in Biology from the Université des Sciences et Technologies de Lille (Lille I). He earned his Ph.D. degree from the Pierre and Marie Curie University (Paris), working on hepatitis C virus infection of primary human hepatocytes. In 2010, he joined the Liver Disease Group of Dr T Jake Liang at the National Institute of Health (NIH, Bethesda, USA) as a postdoctoral fellow. There, he focused on developing new relevant in vitro and in vivo models for hepatitis B (HBV) and hepatitis C virus (HCV) infection using human pluripotent stem cell-derived hepatocytes (also called “HLCs”). In 2015, he joined the Institute of Experimental Virology at TWINCORE, where he studied the innate immune response to HCV infection in HLCs. Arnaud Carpentier now focuses his work on deciphering restriction mechanisms and host factors associated with hepatitis D virus (HDV) infection in HLCs.
