I obtained my BA (Hons) in Linguistics and Language Pathology from Essex University in 1986. I then completed an MSc in Computation at UMIST in 1987, before undertaking a PhD at the University of Leeds in 1988. During my PhD I undertook some part-time teaching at the University of Salford. My PhD was completed shortly before my appointment to Lecturer at the University of Sheffield in 1992. I was promoted to Senior Lecturer in 2001, to Reader in 2004, and was awarded a personal chair in speech sciences in 2016.
