Background
Dr. Jing Han is a research microbiologist (staff fellow) in the Division of Microbiology at FDA’s National Center for Toxicological Research (NCTR) in Jefferson, Arkansas. Dr. Han received a Bachelor of Science degree in veterinary medicine from Shandong Agricultural University and a Master of Science degree in veterinary microbiology and preventive medicine from China Agricultural University. Her research focused mainly on the development of an ALV (Avian Leukosis Virus) detection kit, where she expressed and purified the ALV P27 protein, then developed mouse anti-P27 monoclonal antibodies and rabbit anti-P27 polyclonal antibodies using the purified P27 as antigen. Using the monoclonal antibodies and polyclonal antibodies that Dr. Han developed, an ALV detection kit was developed and has been commercialized in China and extensively used by poultry farms to detect virus antigens and antibodies in serum or egg samples. Dr. Han then earned a Ph.D. in veterinary microbiology at Iowa State University, where she worked on the identification of novel mechanisms involved in the emergence and fitness of fluoroquinolone (FQ)–resistant Campylobacter.
Dr. Han joined NCTR as a postdoctoral fellow and conducted research mainly related to the mechanisms that facilitate the spread and persistence of virulent and antimicrobial-resistant bacteria. Following her postdoctoral fellowship, Dr. Han joined the Public Health Laboratory of the Arkansas Department of Health as a microbiologist, where she conducted microbiological testing and interpretation of results, data analyses, and performed administrative duties. In 2015, Dr. Han rejoined NCTR as a research microbiologist where she served as a leading investigator on a project funded by FDA’s Center for Tobacco Products focusing on smokeless tobacco-associated microbiology. Currently, Dr. Han serves as the principal investigator of an NCTR protocol that aims to develop improved databases for Salmonella virulence, gene identification, and plasmid characterization and to develop the analytical tools for data analyses.
Research Interests
Dr. Han’s main research interests are in the fields of antimicrobial resistance, pathogenesis of foodborne pathogens, and genetic characterization of enteric bacteria using molecular techniques. Her research projects at NCTR include:
- Genetic characterization of antimicrobial resistance and associated genetic factors in Salmonella serovars associated with food animals and invasive human infections
- Sequencing and functional analysis of plasmids isolated from multi-antimicrobial resistant bacteria
- Evaluation of the relative selective potential of antimicrobial agents to trigger the dissemination of antimicrobial resistance and virulence factors to susceptible Salmonella
- Investigation of microbial populations in different tobacco products
