Postdoctoral positions are immediately available to determine the importance and underlying molecular mechanisms of viral and host interactions in the infection, replication, and morphogenesis of hepatitis B virus (HBV) and SARS-CoV-2 and their pathogenesis in vitro and in vivo. Other interesting research areas include innate immune evasion by SARS-CoV-2, HBV/HCV-induced hepatocellular carcinoma (HCC) particularly in hepatic cancer stem cells (CSCs), and antiviral and anti-cancer drug discovery. Innovative research approaches developed in the lab include mouse models of HBV/HCV infection and replication, robust cell culture models of HBV/HCV/SARS-CoV-2 infections, genomics, proteomics, bioinformatics, gene-editing (CRISPR/Cas9) system, cell biological, gene-knockout and immunological technologies. Candidates with research interests and experience in molecular virology, molecular biology, stem cell research, genome-wide profiling of transcriptome, genomics and proteomics, animal modeling of disease, and/or tumor biology are encouraged to apply. Salary and fringe benefits are highly competitive and commensurate with research experience. Applicants with Ph.D., M.D., or equivalent degrees should send their CVs along with contact information of three referees to: Dr. George Luo at gluo@uab.edu. The Department of Microbiology, Center for AIDS Research (CFAR), and the Comprehensive Cancer Center at the University of Alabama at Birmingham (UAB) School of Medicine are national and international leaders in biomedical research. UAB also offers an unusually interactive research environment with many other multidisciplinary centers, including Center for Structural Biology, Center for Clinical and Translational Sciences, Center for Emerging Infections and Emergency Preparedness, Liver Center, Transplant Institute, and campus-wide Program in Immunology. Birmingham and its surrounding areas are very attractive for single and family life with excellent school systems and affordable housing. UAB is an equal opportunity employer.
