Hiroshi Kataoka (ja: 片岡 宏誌) is a Japanese entomologist and a professor emeritus at the University of Tokyo, Japan.
Notably, his two mentors received the prestigious Japanese Academy Prize (日本学士院賞) for their work on the purification and identification of PTTH, a milestone that had eluded many predecessors.
Of the 20 initial members at the Kashiwa Campus start-up, three were awarded the Japan Academy Medal—Kazushige Touhara,[16][17] Yuki Oka,[18][19] and Naoki Yamanaka[20]—Japan’s highest honor for young researchers to date.
Hironori Ishizaki, one of his mentors, noted in his autobiography that Kataoka had both the temperament to embrace difficult challenges and a boldness.
He then completed a post-doctoral fellowship at the Zoecon Research Institute, Sandoz Crop Protection, in Palo Alto, California, starting in April 1986.
