Beatriz Barragan, PhD Candidate
Beatriz is a Colombian PhD student in the Speech and Hearing Science Department at ASU. She has a MA in Experimental Psychology from Universidad Nacional de Colombia, and a MS in Clinical Research Management from ASU. She is interested in the neurobiological bases of bilingual language production and perception, specifically on how the neural systems for language might be modified by the bilingual experience.
Beatriz has been working on the assessment and development of language tests used to identify bilingual children at risk of language impairment, and on the development and evaluation of a protocol that captures aspects of speech rhythm, and articulatory integrity of Spanish monolinguals and Spanish-English bilinguals with dysarthric speech. Beatriz was recently awarded the Marilyn Miller Quintana Moline Scholarship for the 2015-2016 academic year.
Ashley Adams, PhD Candidate
Ashley Adams graduated from the University of California, San Diego in 2006 with a BA in Psychology. She joined the doctoral program in Speech and Hearing Sciences in Fall 2012 with Dr. Laida Restrepo as her mentor. Her interests include the predictors of literacy outcomes for English language learners with and without specific language impairment and developing appropriate standardized tests and interventions for the Spanish-speaking ELL population. Ashley is the lead research assistant on the EMBRACE project, allowing her to continue to investigate the interplay of dual language learning, embodied cognition and reading comprehension.
Lourdes Martinez Nieto, PhD Candidate
Her research interests include Spanish language development in monolingual and bilingual children, L1 maintenance in subtractive bilingual environments, and exploring new methods for the identification of language impairment in bilingual children.
Beatriz de Diego Lázaro, PhD Candidate
Beatriz de Diego graduated from the Complutense University of Madrid, Spain, with a B.A. in Speech Therapy in 2009. She completed her Master’s Degree in Linguistics at the same University in 2011. In 2013, she graduated from Fontbonne University, St. Louis, MO., with a M.A. in Early Intervention in Deaf Education. Since she graduated with her M.A. in Speech Therapy, she has been working with different populations, mainly children who are deaf or hard of hearing and their families, with an Audio-Verbal approach. Beatriz joined the ASU doctoral program in Speech and Hearing Science in the fall of 2015 thanks to a scholarship awarded by “La Caixa”, Spain. She is interested in studying oral bilingual development of children who are deaf or hard of hearing. She is also interested in Early Intervention services that facilitate bilingual and bicultural development of children and their families.
Ekaterina Smyk, PhD, CCC-SLP
Dr. Smyk is currently an adjunct faculty member at Portland State University as well as a speech-language pathologist in the Hillsboro School District in Portland. Her research has focused upon the areas of typical and atypical language acquisition in bilingual children and identification of language impairment in bilingual populations. Her dissertation project investigated the effects of language impairment on English language acquisition in bilingual children and differentiation between bilingual children with and without language impairment at different levels of English language proficiency. She has also worked on several research projects that investigated the language skills of bilingual children with and without language disorders and the effects of bilingual and English-only intervention on the development of two languages. In addition, she worked on the development and validation of a criterion-based measure of oral language proficiency for bilingual children.
Maria Kapantzoglou, PhD, CCC-SLP
Maria Kapantzoglou, Ph.D., is an assistant professor at Portland State University (PSU) and a certified trilingual speech-language pathologist. Her research focuses on the assessment of language skills in bilingual children with and without primary language impairment. She has a Master in Measurement, Statistics and Methodological Study, and she has worked in federally funded projects to develop culturally and linguistically appropriate assessment tools for Spanish-English speaking children. She has worked with bilingual children in four different countries and in three languages: English, Spanish and Greek. At PSU, she teaches courses on speech and language disorders, and supervises graduate students in the bilingual concentration..
Carol Mesa, PhD
