Hideaki Sena, Ph.D. (瀬名 秀明 Sena Hideaki?, born January 17, 1968 in Shizuoka City) is a Japanese pharmacologist and novelist. Sena was a graduate student at Tohoku University when he wrote his prizewinning debut novel, Parasite Eve.
His most famous novel, Parasite Eve, was adapted into a film and a popular horror role-playing video game by Square. When Parasite Eve was adapted as a video game, Hideaki Sena did not learn the titles plot until it was completed, since the game was a collaboration between Square and his publisher. He is also the author of Brain Valley, for which he won the Nihon SF Taisho Award, and Tomorrow's Robots.
Dr. Sena currently lives in Sendai, Japan where he lectures on microbiology and genre fiction. Sena is a pen name, while the author's real name is Suzuki.
