Main Research
Theoretical and descriptive phonetics:
Serial ordering and motor control of speech production: articulatory dynamics – coarticulation - sensory feedback control of speech - tongue slips
Physiological, aerodynamic and perceptual explanations for phonological universals
Articulatory / acoustic correlations in speech production
Cross-language studies of fricatives

Clinical phonetics:
Instrumental phonetic methods in diagnosis, assessment and rehabilitation of children and adults with phonetic and phonological disorders (particularly in cleft palate, dysarthria, aphasia, hearing impairment and Down's Syndrome)
Aerodynamic and phonological correlates of disorders of fluency (particularly stuttering and cluttering)
Linguistic and motor speech profiling of stuttering behaviour
Development of Electropalatography ( EPG ) for recording and measuring tongue activity during speech
Abnormal sibilant production

Research funding
Principal sources of research funding have included: MRC, ESRC, EPSRC, Scottish Office Department of Health, Lloyds TSB Foundation for Scotland, MacRobert Trust, European Union, British Council
