My current researches have been focusing on 1) Etiology, molecular epidemiology, and pathogenesis of waterfowl diseases. 2) Replication, pathogenesis and host immune responses of viruses in waterfowl (e.g. TMUV, DHV, GPV and DRV). 3) Fundamental investigation of parvoviruses, including infection, viral-host interaction and pathogenicity mechanism. These researches aim to promote animal and human health.
