    Research Interests

    Viruses infect humans, animals, plants, insects, and microbes, and more than 90% of human illnesses are caused by viruses. Animal viruses can cross species boundaries to infect human populations and viral infections of domestic animals can cause an enormous economic and societal impact. Virus replication relies on host cell machineries and thus during infection continuous interaction occurs between virus and host. Virology is the study of the molecular and cellular aspects of such infections and aims to develop control measures for infection of medical and veterinary importance. We use Porcine Reproductive and Respiratory Syndrome (PRRS) virus as a model to study cell-virus interactions and to understand viral evasion strategies against host immune surveillance. We have developed a system called "reverse genetics," and using this system we are able to generate genetically engineered mutant viruses. This tool enables us to study various pathogenic mechanisms and to investigate the role that individual viral proteins play during infection.

    Biography

    • Dr. Yoo studied Veterinary Medicine at Seoul National University, Korea. He completed his Master of Science degree in microbiology at the same institution and moved to Canada for further studies in virology at the medical school in the University of Ottawa. His doctoral advisor, Dr. C. Y. Kang, was a virologist trained in the laboratory of Dr. H. Temin, who received the Nobel Prize for the 'provirus' hypothesis, which led to the discovery of reverse transcriptase. Dr. Yoo's doctoral research involved molecular investigation of the hantavirus genome. He completed his PhD in 1988. Dr. Yoo pursued his post-doctoral training at Vaccines and Infectious Disease Organization under the supervision of Dr. L.A. Babiuk, who now serves as Vice-President for Research at the University of Alberta. Dr. Yoo was appointed professor at Ontario Veterinary College, University of Guelph, and initiated his current research on Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), which has begun to emerge as a new and significant pathogen.
    • Dr. Yoo's career in research is unique as his training and education has taken place in a medical and veterinary setting. His research strengths lie in molecular virology and modern vaccinology, which serve to form the basis of his current research themes and direction.
