Research from the Speech and Language Therapy department

Research and clinical audit are an implicit part of the ethos and commitment of the Speech and Language Therapy department.

Research programmes primarily focus on disorders of communication related to developmental and structural anomalies, and feeding disorders related to oral motor and pharyngeal dysfunction.

Many staff have research projects registered with the Institute of Child Health.

For more information about current research projects and published work please visit our research and publications page in our section for health professionals.

Current registered projects
