Sameer ud Dowla Khan is a Professor of Linguistics at Reed College and co-editor of the Journal of South Asian Linguistics. They lead research in phonetics and phonology, specializing in intonation (prosody), voice quality (phonation), and South Asian languages. As director of Reed College's Lab of Linguistics, they oversee research on diverse languages and their varieties. Their research examines the physical attributes of speech sounds, abstract mental representations, and cross-linguistic patterns. Primary specializations include developing phonological models of Bengali intonation (InTraSAL system), comparative analysis of South Asian languages, and pioneering work on Bangla Sign Language. Khan's work spans theoretical and applied linguistics with strong interdisciplinary connections to cognitive science. Analysis of their 15 most recent publications reveals dominant research trajectories: phonetic documentation of phonation types (breathy/creaky voice) across languages, prosodic typology of South Asian languages, sociophonetic variation in voice quality, and applications in language acquisition/technology. Major methodologies include acoustic analysis, perceptual experiments, and corpus linguistics. Khan teaches undergraduate courses including: Introduction to Phonetics, Phonological Theory, Intonation Systems, Field Methods, and South Asian Languages.
