Child language from a longitudinal and processing perspective, specifically bilingual language development in typically developing children and those with language impairments.
Dr. Raúl Rojas is a leading researcher in the area of bilingual language sampling analysis (LSA) using reference databases via SALT software, as well as specialized longitudinal, large-scale data analysis, and best practices for bilingual speech and language assessment. Dr. Rojas is the Director of the Bilingual Language Laboratory at the Callier Center for Communication Disorders in Dallas, which is conducting two longitudinal projects with bilingual preschool-age children and recently completed data collection on an eye-tracking-bilingual LSA exploratory study. Dr. Rojas recently has published studies of bilingual children’s language development using large-scale databases (e.g., Heilmann, Rojas, et al., 2015; Rojas et al., 2015; Rojas & Iglesias, 2013) and on the use of bilingual LSA (e.g., Iglesias & Rojas, 2012; Peredo, Owen, Rojas, & Caughy, 2015). Dr. Rojas earned his bachelor’s degree at Grinnell College and his master’s and doctoral degrees at Temple University in Philadelphia.
