Eriko Sato is a lecturer of Japanese language at the State University of New York at Stony Brook, where she received her PhD degree in linguistics. She also is the Founding Director of the Pre-College Japanese Language Program as well as the Executive Director of the Japan Center at the same university. When she started her graduate work in 1988, she decided to devote her career to Japanese-language education and research. She studied Japanese and English linguistics and foreign languages, including Chinese, French, and Korean, to prepare herself to be a teacher and researcher who understands students’ linguistic backgrounds and difficulties. She has written many articles for linguistic and education journals, and she has written three books on Japanese language: a textbook for young children, a textbook for college students, and a manual for Japanese/English translators.
