Yoko Aida serves as Project Professor in the Laboratory of Global Infectious Diseases Control Science at the Graduate School of Agricultural and Life Sciences, The University of Tokyo, a position she has held since April 2021. Her academic background includes a degree in veterinary medicine from the Graduate School of Veterinary Medicine at Hokkaido University in 1985, following earlier studies at the Graduate School of Veterinary Sciences and Kitasato University. Aida's research centers on molecular virology, viral infectious diseases, virus control, and immunogenetics within veterinary medicine. She has conducted extensive work on bovine leukemia virus (BLV), including mechanisms of leukemogenesis, identification of BoLA-DRB3 polymorphisms associated with susceptibility or resistance, proviral load control, diagnostic methods such as quantitative PCR assays, and development of prevention strategies. Additional research explores photocatalytic and nanotechnological approaches for inactivating airborne viruses, including influenza and coronaviruses. In 2024, Aida received the Japan Agricultural Science Award and Yomiuri Agricultural Science Award for her contributions to understanding BLV onset mechanisms and establishing diagnostic and preventive measures. She has also been recognized with awards from the Japanese Society of Veterinary Science, the Animal Science Journal, and various regional veterinary and immunology societies for studies on MHC genes, BLV resistance markers, and related topics. Aida maintains affiliations with RIKEN and collaborates on projects involving cattle breeds in Japan and internationally, contributing to numerous peer-reviewed publications on BLV epidemiology, genetic markers, and virus inactivation technologies.
