Deirdre Larsen 

Deirdre Larsen is a third-year doctoral student in the Department of Communication Disorders at Louisiana State University under the mentorship of Dr. Melda Kunduk. She earned a Bachelor of Science degree in 2014 from the University of Montevallo and a Master of Arts degree in 2017 from Louisiana State University. Deirdre received extensive training in pediatric feeding and swallowing disorders at the LSU Pediatric Feeding Clinic as well as training in adult voice and swallowing disorders at the Our lady of the Lake Voice Center. She is currently completing her clinical fellowship at the Our Lady of the Lake Voice Center where she provides service to adults with voice and swallowing disorders and to individuals with cleft palate or other craniofacial anomalies. Deirdre’s research focuses on health and disease of special populations as it relates to feeding and swallowing disorders. Current research includes assessment and treatment approaches for tongue-tie, the influence of gastroesophageal reflux on the infant gut microbiome, and sensory changes in head and neck cancer patients undergoing radiation. Deirdre is also the instructor for Introduction to Communication Disorders.


Barnali Mazumdar

Barnali Mazumdar is a fourth-year doctoral student in the Department of Communication Sciences and Disorders at Louisiana State University (LSU), mentored by Dr. Neila J. Donovan. Mazumdar earned her Master’s in linguistics from India. Her Master’s thesis research led to the adaptation of the Western Aphasia Battery-Revised in Bangla (a language spoken in India and Bangladesh). The limitation of aphasia test adaptation motivated her to further develop a language-specific aphasia assessment in Bangla. Currently, she is pursuing her research on Bangla aphasia test development and teaching her introductory linguistics course at LSU.


Surani Nakkawita

Surani is a fourth-year doctoral student in the Department of Communication Sciences and Disorders at Louisiana State University, where she is mentored by Dr. Neila Donovan. Surani entered the doctoral program with previous work experience in Sri Lanka with individuals with developmental and acquired communication disorders. Surani’s research examines the accessibility of augmentative and alternative communication (AAC) systems for people with aphasia. She is currently a research assistant for Dr. Susan Duncan in the Language Imaging and Brain Research (LIBRe) Lab.


Aswathy Anakkathil Pradeep

Aswathy Anakkathil Pradeep is a first-year (Spring 2020) doctoral student in the Department of Communication Sciences and Disorders at Louisiana State University, supervised by Dr. Susan Duncan. Aswathy completed her MA in Speech-Language Pathology from Edinboro University of Pennsylvania (2019) and her Bachelor’s degree in Audiology and Speech-Language Pathology from Manipal University, India (2017). She is interested in neuro-communication disorders and associated treatment in adults, and her research focuses on transcranial direct current stimulation and treatment of individuals with aphasia. Aswathy hails from the verdant state of Kerala, in the south of India.


Austin Thompson

Austin Thompson is a second-year doctoral student in the Department of Communication Sciences and Disorders with a research interest in speech science. Under the mentorship of Dr. Yunjung Kim, Austin’s research investigates the use of speech science to diagnose and treat individuals with dysarthria, a group of speech disorders caused by various neurological conditions (including Parkinson’s disease and Amyotrophic Lateral Sclerosis). Specifically, he aims to link acoustic measures and their underlying articulatory gestures to inform treatment for individuals with dysarthria. In other words, he explores the connection between how we speak and what we hear. Austin earned a Bachelor of Arts degree in 2016 and a Master of Arts degree in 2018 in Communication Sciences and Disorders from Louisiana State University. In his spare time, Austin enjoys spending time with his dogs, tending to his houseplants, and watching scary movies.


Shanley Treleaven

Shanley Belle Treleaven is a third-year doctoral candidate studying under the mentorship of Dr. Geoffrey Coalson. She earned her Master of Science in Speech-Language Pathology from the University of Alabama, where she also earned her undergraduate degree in Communication Disorders with a French minor. Shanley completed her clinical fellowship as a speech-language pathologist during her first two years in LSU's doctoral program, both in the LSU Stuttering Lab and at The Emerge Center. Currently, her research focuses on executive functioning and its theoretical relationship with stuttering. Her hope is to use empirical evidence to inform clinical practice so that speech therapy can help to improve quality of life for adults who stutter. She has been the primary instructor for both Basic Fluency Disorders and Introduction to Communication Disorders.
