I am a Professor of Hispanic linguistics in the Department of Hispanic and Italian Studies at the University of Illinois at Chicago. I am also a faculty affiliate in the Latin American and Latino Studies Program, the Department of Curriculum and Instruction, and in the Social Justice Initiative. I am also the founding ​​director of the Language in Context Research Group. 

Since 2009 I've served as Executive Editor of the journal Spanish in Context.

Most broadly, I am interested in the promotion of minority languages and multilingualism, particularly via elementary schooling. My work focuses on Spanish in the United States, including factors that influence intergenerational language transmission, connections between language and identity, and heritage language education. Some of my recent research topics include:

* Language development in a dual immersion school
* Spanish use in Chicago quinceañera celebrations
* The use of “Spanglish” in commercially published greeting cards
* Comparisons between Mexican and Puerto Rican Spanish in Chicago
* The language and identity of mixed “MexiRican” individuals
* Teaching heritage languages, particularly Spanish in the U.S.
