My research investigates language acquisition and processing in the visual modality. In particular, I am interested in (1) bilingualism in the Deaf community, (2) the effects of language input on the development of language processing skills, and (3) the effects of the visual modality on the structure and processing of language. I collaborate with departmental colleagues and graduate students on studies of minority language acquisition in the Lobo Language Acquisition Lab.

PIRE - Partnership for International Research and Education
The Partnership for International Research and Education (PIRE) grant is hosted at both Pennsylvania State University and the University of California at Riverside. The goal is to train a diverse workforce of language scientists, many of whom are from underrepresented groups in the STEM workforce, to conduct basic and applied behavioral and neuroscience research as it relates to bilingualism.
UNM is a domestic partner. We focus on bilingualism in communities that use minority languages, signed languages, languages that rely on different orthographies, and bilingualism in learners who have only sparse input to one of their languages.
Here is a list of ongoing projects:
- Cross-language activation during visual word recognition in bimodal and biscriptal bilinguals
- The time-course of cross-language activation in deaf bilinguals
- Effects of iconicity on language processing
- Effects of sparse input on language acquisition and processing
