Sonja Molfenter

Associate Professor

Communicative Sciences and Disorders


Dr. Sonja Molfenter is a clinically-trained Speech Language Pathologist whose research specializes in understanding the physiological features of both normal swallowing and disordered swallowing (known as dysphagia). Swallowing function is commonly disrupted after many conditions including stroke, brain injury, head and neck cancer and spinal cord injury.

Her over-arching research goal is to produce clinically-relevant research to inform front-line clinical practice. Her research focuses on naturally-occurring muscle loss in the pharynx as the result of aging. Dr. Molfenter's work aims to understand the impact of these age-related changes on swallowing function and explore methods to prevent or reverse these changes. Dr. Molfenter also studies changes to swallowing function after cervical spine surgery.

Research Colloquium in Communicative Sciences and Disorders

Students participate in discussion of research topics, AND engage in research out of class with a faculty member. During this time, students are also exposed to examples of scholarly research presented by guest speakers, who are eminent researchers on speech language pathology and related areas. This course is required for 3 semesters for doctoral students but may also be taken by master’s level students for a single semester. Doctoral students doing research with faculty will present results at the colloquium.
