Dr. Castilla-Earls obtained her PhD from the University of Toronto in 2008. She is an Associate Professor in the Department of Communication Disorders and Sciences at the University of Houston. Dr. Castilla-Earls' primary research interests are language development, assessment and disorders in monolingual and bilingual children. Her current research explores approaches to differentiate typically developing bilingual children from bilingual children with language disorders by (a) examining differences between monolingual and bilingual development, and (b) studying the effect of language exposure shifts on bilingual development. Dr. Castilla-Earls’ current research is funded by the National Institute of Deafness and Other Communication Disorders.
