Research Interests/ Research Summary

Our lab current research focuses on  virus characterization, next generation vaccine design for enveloped viruses and development of suitable animal model and novel assays for infectitious diseases, that will benefit  the evaluation of vaccine candidates, anti-viral drug screening and therapautics. Our lab long standing research interest is to carry out innovative scientific research on enveloped viral agents leveraging on the expertise gained from HIV ,Influenza and Paramyxoviruses, thus creating a ' Translational and Systems virology platform'. I have extensive working experiences in enhanced BSL3+ and ABSL3+ lab to work with CDC select agents. Our team have initiated work on SARS-CoV2 viruses and developed SARS-CoV2 pseudovirus neutralization assay. We  are growing, cultivating and characterizating the SARS-CoV2 viruses inside BSL3 facility.Furthermore, we are also conducting immunogenicity and antigenicty assessment of COVID-19 immunogen candidates in mouse model.
