Prof. Surya Paudel is an Assistant Professor (Poultry) at the Department of Infectious Diseases and Public Health, City University of Hong Kong. He is a veterinarian and obtained his PhD degree in poultry medicine from the University of Veterinary Medicine Vienna, Austria in 2015. Prof. Paudel is a resident at the European College of Poultry Veterinary Science within the European Board of Veterinary Specialization. He is also serving as a member of methodology task force for drafting “Veterinary guidelines on antimicrobial use in poultry colibacillosis” in the European Network for Optimization of Veterinary Antimicrobial Treatment (ENOVAT) programme. Previously, he worked as a postdoctoral researcher at Clinic for Poultry and Fish Medicine, University of Veterinary Medicine Vienna (2015-2022). In addition, his work experience includes conservation and management of critically endangered wildlife species, in particular, in restoring the natural population of dramatically declining vultures in South East Asia (2008-2010).
Surya Paudel is interested in research and teaching works related to all aspects of poultry health, especially in understanding host-pathogen interaction, immune response towards infections, epidemiology and prevention of diseases as well as food safety and one health.
