Katherine Christoffersen I am an Associate Professor of Applied Linguistics and Associate Vice Provost for Bilingual Integration at the University of Texas Rio Grande Valley. I earned my PhD in Second Language Acquisition and Teaching and my MA in English Language and Linguistics from the University of Arizona. My teaching and research are closely connected, as I study bilingualism in classrooms and communities. I teach undergraduate and graduate courses in applied linguistics, sociolinguistics, and bilingualism, and I strive to create learning experiences that are research-informed and community-engaged. I co-created the Corpus Bilingüe del Valle (CoBiVa), an online, publicly accessible database of sociolinguistic interviews that documents bilingual language practices in the Rio Grande Valley. The CoBiVa is central to my work; it supports student research, informs my teaching, and serves as a tool for community-based scholarship. I frequently integrate the CoBiVa into my courses and present it as an alternative text, thereby attributing prestige to local bilingual language varieties. My research has been supported by internal and external grants, allowing me to mentor undergraduate and graduate research assistants. Through my work, I aim to promote locally relevant approaches to language education and research.
Julio Ciller I’m an Assistant Professor of Translation in the Department of Writing and Language Studies. I hold a Ph.D. in Hispanic Linguistics from the University of Arizona, and my research focuses on translation pedagogy, language learning and teaching, sociolinguistics, and program administration. I specialize in exploring pedagogical approaches for developing language and translation skills, and I’ve also conducted research on language attitudes within the field of sociolinguistics. As part of my work, I mentor undergraduate and graduate students alongside Dr. Chrisroffersn through the CoBiVa (Corpus Bilingüe del Valle) project, supporting their educational journey as they engage with research early in their academic careers. I also integrate CoBiVa into my courses to explore language ideologies in the context of bilingual communities.
Carolina De Anda Raised in Mexico until age 13, is a 5th-grade Gifted and Talented Dual Language teacher at Carmen Anaya Elementary for the Pharr-San Juan-Alamo Independent School District. She is a first-generation graduate and holds a B.A. in Bilingual Education and Mexican American Studies from the University of Texas Rio Grande Valley. Her advocacy and commitment to her students earned her recognition as 2025 RGV-TABE (Rio Grande Valley- Texas Association of Bilingual Education) Teacher of the Year and 2025 TEA (Texas Education Agency) Title III Rising Star.
Luis (Javier) Arias Raised in Mexico until the age of 17, is currently pursuing a bachelor’s degree in computer science. For the past year, he has been working with the Department of Writing & Language Studies and the Office of Bilingual Integration, where he helps maintain, update, and improve the websites of various projects.
Sara Elizabeth Azua Is a third-generation Mexican American student at UTRGV studying English and Philosophy with a minor in Mexican American Studies. She has a passion for studying languages and cultures, particularly advocating for the preservation of the languages and cultures of her home, the Rio Grande Valley. She worked at UTRGV’s Writing Center for two years and is now a Student Assistant in the Philosophy department. She’s currently conducting a research project with faculty member, Dr. Alex Stehn, to explore the impacts of B3 (bilingual, bicultural, biliterate) philosophy classes on UTRGV students.
Yelzy García I was born in Dallas, Texas, and raised in Nuevo León, Mexico. Growing up in Mexico shaped my cultural identity and gave me a strong connection to my roots, but in 2016 I returned to the United States to continue my education and personal growth. Because of this journey, I proudly consider myself a Mexican-American, embracing both cultures as part of who I am. I graduated from The University of Texas Rio Grande Valley (UTRGV) with a bachelor’s degree in Spanish and a teacher certification, which has allowed me to share my language and culture with others in the classroom. Currently, I am also pursuing my master’s degree in Spanish Linguistics at UTRGV, where I continue to expand my knowledge and prepare for new opportunities in teaching and research. My goal is to contribute to education and help students appreciate the richness of the Spanish language and Hispanic culture.
Jorge Salazar I was born and raised in Matamoros, Tamaulipas. I am currently pursuing my master's degree in Spanish with a concentration in creative writing. I have been working with the Office of Bilingual Integration for a year. I was a student athlete during my bachelor's degree at UTRGV.
Miroslava Rangel I am a bilingual professional whose life has been shaped by a transborder trajectory. I completed my childhood and early schooling in Mexico, while my adolescence and adulthood unfolded in the United States. For more than 13 consecutive years, I crossed back and forth between Mexico and the U.S. to study and work—living in Mexico but pursuing my education and professional opportunities in the United States. This experience allowed me to embrace the best of both worlds, strengthening my identity and deepening my commitment to language and culture. I hold an M.A. in Spanish from The University of Texas Rio Grande Valley, where I also earned my B.A. in Spanish with a minor in Mexican American Studies. My academic focus includes heritage language education, sociolinguistics, and Spanish literature. My previous professional experiences include teaching Spanish, as well as serving in various administrative and support roles in higher education, where I developed skills in program coordination, event planning, and student engagement. Currently, I serve as a Program Assistant in the Office of Student Success at UTRGV, where I support program administration and student initiatives. At the end of the day, teaching and promoting Spanish is my personal act of resistance, uplifting the voices of our communities in the United States.
