My research focuses on the prevention and control of major and emerging infectious diseases in livestock, poultry, and aquatic animals. I am particularly interested in veterinary pathology, immunopathogenesis, host–pathogen interactions, antimicrobial resistance, and animal health management. My work aims to understand how bacterial, viral, and parasitic pathogens interact with the host immune system and contribute to inflammation, tissue injury, and disease progression. I also investigate Chinese veterinary medicines, natural products, and bioactive compounds with immunomodulatory, anti-inflammatory, antimicrobial, antiviral, and antioxidant activities. By integrating veterinary pathology, immunology, microbiology, pharmacology, and natural product research, my research seeks to develop safe, effective, and sustainable strategies for improving animal health and controlling infectious diseases.
