Dr. Catherine Lemmi is an assistant professor of education who teaches courses on Literacy Development and Equity and Access in Education at California State University, Chico. She earned her PhD in curriculum and teacher education from Stanford University, with a focus on language, literacy, and science education. Prior to her PhD, she completed her California Single Subject Teaching Credential in Biology with a Cross-cultural Language and an Academic Development (CLAD) authorization also from Stanford. She has over 10 years of experience in public schools serving in various roles including as an ESL teacher in a Japanese middle school, a science teacher at Sequoia High School in Redwood City, California, and a substitute teacher in Memphis City Schools (now Shelby County Schools) in her hometown of Memphis, Tennessee. Additionally, she has served as a cooperating teacher and supervisor of teacher candidates for the Stanford Teacher Education Program as well as a supervisor for the School of Education at Chico State. Her interdisciplinary research uses mixed methods to explore the relationships between language, ideology, and teacher practice in content area classrooms, especially in STEM subjects. Her recent work investigates the role of language ideologies and hybrid language practices in STEM education for bi/multilingual and heteroglossic communities, with an asset-focused approach to students’ language repertoires. Her goal as a teacher educator is to support teachers to provide equitable, relevant, and humanizing learning experiences for all students in their classes.
