Coalson_photo_NSA

Geoffrey A. Coalson is an Assistant Professor in the Department of Communication Sciences and Disorders at LSU, and the director of The LSU Stuttering Lab established in Spring 2014. His research focus is the contribution of phonological, phonetic, and linguistic factors to stuttering in children and adults. Current projects include differences in working memory skills and word-learning abilities in adults who do and do not stutter. Dr. Coalson also teaches introductory and intensive courses in Fluency Disorders at LSU, serves as chapter leader for the New Orleans chapter of the National Stuttering Association (NSA), and is an active member of the two neighboring NSA chapters in the Southern Louisiana (Baton Rouge and Lafayette).

Graduate Lab Assistants (2016-2017)

Guillot_H
Hailey Guillot is from Marksville, Louisiana and is aCommunication Disorders master’s student in her second year. Hailey works at a clinic that serves children with autism as well as children with speech disorders, and is currently assisting in research at The LSU Stuttering Lab. While assisting in research at the laboratory, Hailey explored the relationship between knowledge of multiple languages and stuttering, and has presented her research at the University of New Mexico and Louisiana State University through the McNair Research Scholars Program.  She recently successfully defended her master’s thesis titled “Medication Use in Adults Who Stutter” under the direction of Dr. Coalson.

Joseph Moegelin is from North Andover, Massachusetts, about 30 minutes north of Boston. He is a member of the LSU Communication Sciences and Disorders graduate class of 2017 and is interested in working with the pediatric population in a school setting upon graduation. He attended the University of Massachusetts Amherst and obtained his bachelors degree in Communication Sciences and Disorders in 2013. Upon graduating, he worked as a speech and language assistant for 2 years in public schools throughout Massachusetts. He is a person who stutters and was excited to learn that LSU had a stuttering lab! He attended speech therapy for my stutter throughout my school years. He says, “Dr. Coalson has been an amazing mentor and professor during my time here at LSU. His knowledge of stuttering and dedication to research is unparalleled. Thank you for any interest you may in contributing to stuttering research!”

Kuylen_A
Amanda Kuylen is a first year graduate student from Abita Springs, Louisiana. She will graduate in 2018 with a M.A. in Communication Sciences and Disorders. Her professional interests include cognitive-communication disorders, dysarthria, fluency, and feeding. Her personal interests include travel, reading, and cooking.  Amanda is very enthusiastic to see the research aspects of speech-language pathology within The LSU Stuttering Lab.


Undergraduate Lab Assistants (2016-2017)

Francesca Tusa volunteered as an undergraduate research assistant in the LSU Developmental Stuttering Laboratory from 2015-2017. She graduated LSU in May of 2017 with a B.A. in Communication Sciences and Disorders and a minor in Leadership Development. During her undergraduate time at LSU, Francesca was active within the COMD department and served as NSSLHA’s student liaison. Francesca also conducted undergraduate research within the LSU Stuttering Lab and presented her senior research project, Recruitment of Adults Who Stutter to Participate in Research, at LSU Discover Day in April of 2017. Francesca is currently pursing her Masters degree in Communication Disorders and aspires to work as a Speech-Language Pathologist in a hospital-setting.

Katelynn Lee is a senior from Baton Rouge, Louisiana. She is majoring in Communication Sciences and Disorders with a minor in Sociology. Katelynn currently works at the LSU ITS Help Desk, and she is assisting with research at The LSU Stuttering Lab. She hopes to gain experience in the research process of language processing as well as have the opportunity to interact with different peers. Katelynn is an active member of LSU-NSSLHA, LSU Student Activities Board, and Minority Women’s Movement. She has taken on leadership roles in becoming the Social Chairperson for the Southern LA Affiliate of the National Black Association for Speech-Language and Hearing as well as a COMD Ambassador for LSU. Over the summer, she will be working with children at Camp Dynamics where she will helping kids diagnosed with autism, ADHD, dyslexia, and developmental delay to enhance socially, mentally, and spiritually in a fun environment. After Katelynn graduates in December 2017 with a B.A. in Communication Sciences and Disorders, she plans to attend graduate school with the intent of becoming a future speech language pathologist with a concentration in stuttering and feeding.
