Santiago Gualapuro is an Assistant Professor in Spanish Linguistics at SIU's School of Languages and Linguistics. He earned his Ph.D. in Hispanic Linguistics at The Ohio State University in 2023. He is an Otavalo Kichwa from Northern Ecuador. His primary research interests concern the sociolinguistics of indigenous-colonial language relationships in Ecuador, Kichwa-Spanish language contact and its effects in Kichwa, indigenous ideologies, writing systems, and language activism in indigenous languages.


Santiago's primary goal is to work in Kichwa's language revitalization alongside Kichwa activists in Ecuador. He is a founding member of the Kichwa Institute of Science, Technology, and Humanities (KISTH Foundation). Under KISTH, he has directed novel projects in Kichwa language revitalization. Under his leadership, KISTH conducted the first Kichwa Science Bee competition in partnership with International Competitions and NGOs based in the United States. At SIU, he is envisioning to build a center for studying indigenous languages in the Americas.

Katherine Martin

Associate Professor

Katherine Martin

Faner 3042
(618) 453-3410

Katherine I. Martin is an associate professor in Linguistics at Southern Illinois University Carbondale and head of the APPLES (Applied Psycholinguistics in Literacy, Education, & Second Language) Lab, part of the Saluki Linguistics Laboratory Consortium. Originally from Michigan, she earned an AB in Brain, Behavior, and Cognitive Science from the University of Michigan and an MA and a PhD in Linguistics from the University of Pittsburgh. She has been at Southern Illinois University Carbondale since 2015. 

Dr. Martin works primarily in the fields of TESOL and second language acquisition. Her research focuses on second language literacy development, particularly the influence of writing system on word recognition and spelling; vocabulary learning; and the influence of individual differences such as working memory, phonological awareness, and foreign language anxiety. She is also interested in the complexities of coding second language data (e.g., in spoken data, how do we distinguish an accent versus an incorrect response? In written data, how can we distinguish spelling versus grammatical errors?) and extending the use of research instruments originally developed for monolingual populations to multilingual individuals. 

Her current projects include a detailed examination of spelling skills in users of English as a second language and examining the time-course of word recognition and sentence reading using priming and eye-tracking methods. She also has active projects with students and former students looking at teachers’ familiarity with foreign language reading anxiety and comparing the efficacy of various strategies for learning foreign language verbs.  

She teaches courses in multilingual education, language assessment, research methods, introductory linguistics, professional development, and second language reading and vocabulary. When not involved with academic work, she enjoys hiking, traveling, reading, and spending time with her husband and two pugs.

Rachel Olsen

Assistant Professor of Practice - TESOL

Rachel Olsen

(618) 453-3418

My first introduction to linguistics and TESOL came during my Cambridge CELTA and developed over the next several years as I taught EFL abroad. This experience led me to pursue my MA in Applied Linguistics at SIUC and then my PhD in Linguistics at the University of Georgia, where my research focused on how people express themselves socially and emotionally through phonetics (i.e., the way the sounds of language are produced and perceived). My current interests include the role of emotion in language and learning in the second language classroom as well as best practices in TESOL composition and grammar.

I have presented my research at a wide variety of conferences including meetings of the Linguistic Society of America, the American Dialect Society, the Acoustical Society of America, and New Ways of Analyzing Variation. My work on sociophonetic variation has been published in the Journal of English Linguistics, the Journal of the Acoustical Society of America, and Proceedings of Meetings on Acoustics, and my work on emotion has been published in the journal NeuroImage.
