From the first year of his Master’s degree in 1988 to the completion of his PhD at Tokyo University of Fisheries in
1993, Dr. Yoshizaki’s primary research focus was on the establishment of a transgenic system for commercially
important fish species. In 1993, he undertook a post-doc in Dr. Reynaldo Patino’s lab at Texas Tech University
where he worked on the molecular mechanisms underlying steroid-induced oocyte maturation in Xenopus and
fishes. In 1995, he moved back to Tokyo University of Fisheries as an assistant professor where worked on germ
cell manipulation and fatty acid metabolism in fish. In 2013, he became a professor at Tokyo University of Marine
Science and Technology.
