  • Evaluation of the interaction using histopathologic lesions scoring of bursal lesions and RT-PCR/ RFLP.
• Ph.D. in Veterinary Medicine
  • Studied the short- and long-term pathogenicity of Turkey arthritis reovirus (TARV) in turkeys and in chickens, virus pathogenesis and cytokine immune responses in TARV-infected turkeys.
• Further Research Experiences
  • Surveillance and experimental studies to investigate the role of enteric viruses in poult enteritis complex in Minnesota.
  • Diagnostic research on avian influenza virus, Newcastle disease virus and oncogenic viruses in poultry production in Egypt.
  • Experience with sequencing technology, Sanger sequencing, next generation sequencing (library prep, DNA, RNA seq, data analysis).
  • Vaccine research (Killed, live and recombinant vaccine development).
