Autism Screening Research

We are conducting a study to identify children (16-36 months old) who may be at risk of autism. Currently we are recruiting Vietnamese families who have children age between 16- and 36-months old. If you want to know more about the study or to participate in the study, please contact HyeKyeung Seung, Ph.D., CCC-SLP at (657) 278-7175, or email:

Bilingual Speech Sound Development Research

Our research project is to examine how bilingual children acquire speech sounds for both languages.  Currently, we are recruiting Korean-English bilingual children who are between 4 and 5 years of age. If you’d like to know more about our study or to participate in the study, please contact Minjung Kim, Ph.D., CCC-SLP at (657) 278-3927, or email:

Motor Learning Research

Dr. Weir-Mayta and his student's research focuses on the cognitive and motor processes that contribute to the speech production and speech motor learning in healthy older adults, individuals with Parkinson's disease (PD), and other motor speech disorders. Current projects include: 1) Age-Based Speech Motor Learning Differences; 2) Feedback Frequency and Speech Motor Learning in individuals with PD; 3) Self-Controlled Feedback in Speech Motor Learning; and 4) Practice Schedule Impact on Speech Motor Learning in individuals with PD. Dr. Weir-Mayta and his team of students are certified in LSVT and welcome individuals with PD to contact him if interested in therapy. Anyone interested in being a study participant are also encouraged to contact him at

Community-Based Participatory Research (CBPR)

To promote student learning outcomes and prepare them for high-quality services to diverse client populations, Dr. Tsao devotes most of her endeavors on “Community-based Participatory Research (CBPR). The CBPR involves several high impact practice (HIPs) such as peer-to-peer mentoring program, service-learning project, and cross-cultural/cross-linguistic study abroad program, and outreach to minority communities project. It not only provides students with beyond classroom experiential learning, but it also benefits the community partner and serves the community.  If you are interested in gaining hands-on experience in research, cross-cultural/cross-linguistic real world experience, or making a difference in the community, you are encouraged to partake in any of the above programs or projects by contacting me at

Bilingualism and Speech Laboratory

The Focus of this laboratory is to understand influence of first language (L1) and second language (L2) interaction on bilingual speakers' production and perceptual behaviors. The current research projects fall under two related categories. A group of projects explore physiological evidence of L1-L2 interaction in lexical stress and phoneme production. A second category focuses on psychosocial consequences of nonnative accent in bilingual speakers and also in listners. Please contact Dr. Rahul Chakraborty at (657) 278-3108 or  for any inquiries.

Augmentative & Alternative Communication (AAC) Research

Dr. Lisa Erwin-Davidson and Dr. Russell Johnston are combining research interests that employ both quantitative and qualitative approaches to examine the language acquisition and concept word learning of children with complex communication needs who require aided AAC and are expected to participate in their academic curricula within their self-contained and inclusive educational settings. Graduate and undergraduate students are currently being recruited to participate in a multi-classroom community-engaged project. This interdisciplinary project is designed to collaborate with, and learn from, preschool instructors who will be educating children with moderate to severe disabilities and complex communication needs. Our research is focused on identifying areas of instructional need for preschool and school-age students who require aided AAC systems and arrive to school with a range of communication, language and early literacy needs.
