Ali Çağan Kaya is a high-honors undergraduate researcher in the Department of English Linguistics at Hacettepe University. His primary research interests encompass experimental phonetics (acoustic phonetics), psycholinguistics, and computational tool development. His research focuses specifically on Turkish vowel formants, employing experimental methods such as eye-tracking and pupillometry. He served as a research intern at the Ankara University Brain Research Center (AU-BRC), where he acquired proficiency in complex data modeling utilizing computational tools and environments like Praat, R (LMM, GAMM), and Python. He is currently executing a project titled "The Vowel Frequencies of Standard Turkish," funded by the TÜBİTAK 2209-A program. To provide methodological contributions to the literature, he has developed open-source software, including "VowSpace" (a vowel formant analysis and normalization tool) and the AI-powered "Praanscribe" (a semi-automatic segmentation tool for Praat). Furthermore, he is the co-author of a meta-analytical chapter on Turkish vowel formants in the volume Contemporary Studies in Linguistics I. Alongside his experimental research, he also serves as the President of the Hacettepe University Linguistics Community.
