Adam J. Hogan

Adam J. Hogan is a third-year doctoral student studying under Dr. Todd A. Gibson. He earned his MA in Communication Sciences and Disorders from Louisiana State University in 2004, after which he worked as a school-based speech-language pathologist for sixteen years before returning to LSU. During this time, Adam served as a member of the assistive technology support teams in Baton Rouge, Louisiana, and Kingwood, Texas; evaluated and treated children with complex communication needs in preschool through high school; and spent the last three years of his clinical career at a kindergarten campus in Zachary, Louisiana. His research interests include child and adult second language acquisition, second language phonological acquisition; the utility of nonword repetition as a tool to aid in the identification of language impairment in bilingual children. Additionally, given the scarcity of bilingual speech-language pathologists in the United States, Adam is also interested in identifying and improving methods of bilingual speech and language evaluation when conducted by monolingual speech-language pathologists.

Tahmineh Maleki

Ella Tabari

Ella Tabari is a Ph.D. student in the department of communication sciences and disorders and a research assistant at the Human Neurophysiology & Neuromodulation Lab under the mentorship of Dr. Johari. She completed her first Ph.D. in Neurolinguistics at Universidad Autónoma de Madrid where she conducted her research in understanding the Neural Signature of Bilingualism using the Magnetoencephalography (MEG) technique. Currently, her research focuses on the validation of HD-tDCS for improvement of speech and limb motor control in healthy older adults and individuals with Parkinson’s disease. Her research centers around utilizing EEG and HD-tDCS/tACS to study the neural correlates of language. Specifically, she investigates how these neurophysiological methods can shed light on the mechanisms underlying language processing and its disorders. Her multidisciplinary approach, encompassing neuroscience, experimental psychology, and linguistics, allows her to explore new frontiers and develop innovative solutions that can positively impact individuals with communication disorders.

Jesica R. Sykes

Hi, I’m Jes, an Autistic speech-language pathologist and PhD student in Communication Sciences with a minor in Sociocultural Anthropology at Louisiana State University (LSU). I work primarily under the mentorship of Janet A. Norris, Ph.D., CCC-SLP in the Language Intervention Lab. My scholarship and advocacy combine qualitative, participatory, and visual methodologies in autism research to examine how communicative environments affect social participation, friendship, and inclusion; communication access; and quality of life for autistic people. Gaining a greater understanding for the various ways marginalized people are underrepresented in higher education, while recruiting, and retaining autistic and neurodivergent individuals in academia to ensure our voices are heard in future research is of paramount importance to me. Outside of work, I enjoy music, running, reading, writing, and petting/feeding any animal I see!

Muhammad Ayyaz

Muhammad Ayyaz embarked on his doctoral journey in Fall 2022, dedicating his research to the field of adult bilingual communication disorders. He completed his undergraduate studies at Forman Christian College Lahore, earning a Bachelor of Arts degree and later, he pursued a Master of Science in Applied Linguistics from The University of Management and Technology, Lahore. He is also a graduate of the UT-CELT program at The University of Texas at Austin. Muhammad's primary research interest lies in exploring evidence-based practices for adults who are bilingual and experience communication disorders. With a focus on dual-language phonological patterns, currently, he is investigating the impact of the mora on bilingual language production and how it influences the exact temporal coordination of syllables in native and non-native languages. To that end, driven by his passion for helping others, he envisions a future where he develops innovative tools tailored to the unique needs of bilingual individuals grappling with speech and language disorders.
