  • BS, MS, PhD

Recombinant subunit vaccine and diagnostic reagent development; characterization and molecular subtyping of bacteria of medical importance; molecular mechanism of microbial pathogenesis; evolution and dissemination of drug resistance among bacterial pathogens.

Supervise the diagnostic bacteriology, mycology, parasitology, bacterial disease serology and part of diagnostic molecular microbiology laboratories that provide services to veterinary medical practioners, college and university researchers and valuable case material for teaching veterinary medical and graduate students. Participate in teaching veterinary bacteriology. Other activities include consultation with clinicians, students, private practitioners, and researchers; development of new tests; maintenance of quality control; and interpretation of diagnostic test results.
