Bio and Expertise

Bio
Abigail (Abby) Delehanty, Ph.D., CCC-SLP is an Assistant Professor and Program Director for the Language Disorders and Autism Clinic in the Department of Speech-Language Pathology at Duquesne University. She received her bachelor's and master's degrees in Communication Sciences and Disorders at the University of Texas at Austin and a Ph.D. in Communication Science and Disorders from Florida State University.

Dr. Delehanty is a certified speech-language pathologist with clinical experience serving toddlers, preschoolers, and school-aged children and adolescents with communication disorders. Before returning to pursue the research doctorate, she practiced as a public school-based speech-language pathologist serving children from ages 2 ½ to 22. For the last five years of her career in the schools, she served as an SLP on a full-time, multidisciplinary autism evaluation team, conducting weekly developmental screenings in the community and connecting more than 100 children with school-based services each year. Dr. Delehanty's clinical and research interests include studying and promoting social communication development in children with communication delays and autism, reducing the age of identification of communication delays and autism in young children from diverse cultural backgrounds and underserved areas, technology-supported screening, assessment, and intervention, and increasing understanding of the mechanisms underlying the link between gesture and language development, including language comprehension and responsive parenting.
