Ralph Leon Rose is an Associate Professor at Waseda University's Faculty of Science and Engineering, specializing in computational linguistics and second language acquisition. Holding a Ph.D. in Linguistics from Northwestern University (2005), his career spans over 30 years in language education across Japanese institutions including Gunma Prefectural Women's University and Notre Dame Seishin Women's Junior College. His research focuses on hesitation phenomena , speech fluency measurement , and computer-assisted language learning . Recent work analyzes filled pauses across languages, develops AI-powered vocabulary assessment tools (VocQGen), and investigates ethical implications of disfluencies in AI speech. His publications reveal consistent exploration of how temporal speech variables affect second language perception and production. AY2018 e-Teaching Award from Waseda University Cognitive Science Fellow at Northwestern University Rose leads multiple research projects including Automatic generation of vocabulary quiz items and Modeling speech fluency for e-learning . His lab develops practical tools like Fluidity (real-time fluency feedback), JESPR (self-paced reading tasks), and the Crosslinguistic Corpus of Hesitation Phenomena . As an active member of ISCA, IEEE, and EUROCALL, he contributes to shaping ethical standards in AI speech applications while maintaining strong industry connections through regular media appearances and conference keynotes.

Miyuki Sasaki is a Professor at Nagoya City University's Faculty of Education and Integrated Arts and Sciences, School of Education, specializing in second language writing, language assessment, and the effects of study abroad experiences. With a PhD in Applied Linguistics from UCLA and extensive research experience, she has made significant contributions to understanding L2 writing development and assessment. Educational Background: PhD in Applied Linguistics, University of California, Los Angeles MA in English Education, Hiroshima University BA in English Education, Hiroshima University Additional studies at Georgetown University in Teaching English as a Second Language Professor Sasaki's research focuses on the longitudinal development of second-language writing ability, the effects of raters' values and belief systems on composition evaluations, and sociocultural factors affecting L2 writers' motivation. Her work takes an ecological-historical approach to understanding multilingual writing development, examining how learners' experiences across different languages and contexts interact to shape their writing abilities. Recent research has increasingly incorporated technology, exploring AI tools like ChatGPT in writing assessment and the impact of machine translation on writing instruction. Her publication trends show a consistent focus on longitudinal studies of writing development, with increasing attention to technology-mediated language learning and assessment. The research demonstrates a progression from examining individual writing processes to investigating broader sociocultural and technological influences on L2 writing. Recent work has particularly emphasized the ecological context of writing development and the intersection of writing with other language skills. Scientific Awards: Special Grant for the Promotion of Research (2019) Nagoya City University Highest Ranked Paper Award (2018) Abe Fellowship for international research (2016) UCLA Nida Award for best qualifying paper (1990) Rotary International Foundation scholarship (1984) Ministry of Education scholarship for University of Michigan (1980) Professor Sasaki has served on numerous editorial boards including the Journal of Second Language Writing, Language Testing, and TESOL Quarterly. She has coordinated AAAL conference strands and served on TOEFL and TOEIC technical panels. Her research projects have been consistently funded by Japanese academic institutions, with current work examining third-language study abroad effects and multilingual writing development. She teaches courses in second language writing, applied linguistics, and English communication, mentoring the next generation of language education researchers.
