Early Life and Education
Shirai was born in Tokyo, Japan. After graduating from the English Department of the Faculty of Foreign Languages at Sophia University, he worked as a teacher at Urawa Municipal High School. He completed a master's degree in TESL (Teaching English as a Second Language) and a doctoral degree in Applied Linguistics at the University of California, Los Angeles (UCLA). He holds a Ph.D. in Applied Linguistics.
Shirai has held various academic positions throughout his career. He served as an assistant/associate professor of English at the Faculty of Foreign Languages at Daito Bunka University, a visiting associate professor in the Department of Modern Languages at Carnegie Mellon University, an assistant professor in the Department of Modern Languages at Cornell University, an associate professor (tenured) in the Department of Asian Studies at Cornell University, a visiting professor and professor in the Department of Japanese Studies at the Chinese University of Hong Kong, and a professor and head of the Linguistics Department at the University of Pittsburgh.
He currently holds the position of professor at Case Western Reserve University. Shirai also served as the third president of the Japanese Society for Language Sciences (JSLS). Shirai is an Associate Editor of the academic journal First Language and Frontiers in Psychology, a member of the editorial board of the International Review of Applied Linguistics in Language Teaching, Korean Language in America, and the Journal of Cognitive Science.
His research interests primarily revolve around language acquisition theories (tense-aspect) .
He has provided functional/cognitive linguistic explanations for the acquisition of tense-aspect, which were predominantly explained through generative grammar, and proposed several alternative hypotheses.
Shirai advocates for the establishment of an "evidence-based society" by utilizing scientific findings to address erroneous beliefs, discrimination, and prejudice. He argues that the minimum conditions necessary for language acquisition are "input + the need for output", and that language learning occurs through mental rehearsal if these conditions are met. He challenges the language acquisition theories based on generative grammar and proposes alternative hypotheses.
