Current research and/or projects
Dr. Ji’s work focuses on HIV Drug resistance, HIV Genetics, HIV viral evolution, Molecular HIV epidemiology, and Next generation sequencing.
Research and/or project statements
- Development and implementation of next generation sequencing (NGS)-based HIV drug resistance (HIVDR) testing technologies
- Development of a universal, full-length genome sequencing protocol for HCV and HIV based on oligonucleotide capture enrichment and next-generation sequencing
- Revolution of molecular viral characterization strategies in support of enhanced viral disease outbreak investigation and surveillance in the next generation sequencing era
- A key initiator and the organizing committee chair of the international symposium for NGS-based HIV drug resistance testing series since 2017.
- contributes greatly to the standardization and operationalization of such assays for frontline HIVDR lab testing for both research, surveillance and patient care purposes
Professional activities / interests
Supervised graduate students, co-op students and postdoctoral fellows.
