Dr Anna Blackwell, BSc, PhD

I graduated from the University of Bristol in 2009 with a BSc in Psychology. Following my degree I worked as a learning support assistant at a secondary school in Bristol gaining an in depth knowledge of the practical implications of speech and language impairment for children both academically and socially.

In 2011 I joined the Bristol Speech and Language Therapy Research Unit as a PhD student as part of the Child Talk programme grant. My PhD study used a case study methodology to investigate the dynamics of the relationship between parent and child language for preschool children with early language delay from a developmental perspective. I worked closely with four families over a 12-month period and used a range of methods, including interviews, parent report, observations and the LENA system, which can record a full day of talk from a child’s home environment and automatically analyse the audio.

During my time at the Unit, I developed a strong interest in using both qualitative and quantitative methods, as well as systematic reviewing, to understand what interventions work and for whom. I have subsequently used these skills to explore public health interventions in both academic and third sector organisations.

Dr Rebecca Coad, BSc, MSc, PhD

BSLTRU Director of Operations

I have worked at Bristol Speech and Language Therapy Research Unit from January 2011to April 2018, most recently as Director of Operations. In addition to this role I worked as the Research Development Manager within the Research & Innovation office at North Bristol NHS Trust and have an Honorary Lecturer position at the University of Bristol, which I continue to do.
My background is in developmental biology and cell therapy, working as a Research Associate at the University of Minnesota USA, before making the move from academia to research management in 2009. My expertise lies in the development, set-up and management of research within the NHS; particularly contract and financial management, obtaining regulatory approvals, delivering complex programmes of research both within acute and primary care settings, people management and strategic planning. My interests lie in maximising the impact of research and ‘adding value.’ I have a particular interest in public patient involvement, specifically how to make it ‘meaningful’ and developing methods for capturing the value/impact.

Ms Sophie Cottrell, BA, MSC, MRCSLT

Specialist Speech and Language Therapist

I qualified as a Speech and Language Therapist from City University in 1998 and since that time I have worked with adults with acquired neurological disorders in a variety of settings. My primary interest is in the area of aphasia and I have recently been fortunate to receive funding for a project looking at the use of mindfulness and other cognitive behavioural therapy techniques and their impact on people with aphasia.
I have also carried out research into information-giving for people with aphasia on stroke wards, which culminated in the publication of ‘Stroke Talk’, an aphasia-friendly resource for people in hospital following stroke.

Current Research

Systematic review: Are mindfulness and other CBT techniques effective in improving communication in people with acquired, non-progressive aphasia?

Professor Pamela M. Enderby, MBE DSc (Hons), PhD, MSc, FRCSLT

Emeritus Professor of Community Rehabilitation

I am Emeritus Professor of Community Rehabilitation at University of Sheffield.  I qualified as a Speech and Language Therapist in 1970 and from an early stage in my career combined research with clinical practice. My PhD was awarded by Bristol University in 1983 where I studied assessment processes of dysarthria.

Prior to coming to Sheffield I held several positions in speech and language therapy in Bristol, instigated the establishment of the first AAC centre in Frenchay Hospital and established the speech and language therapy research unit there. I am proud that I was able to stimulate the first National Speak Week in 1986 which was precursor to other initiatives aimed at improving public awareness of the difficulties of those with speech, language and communication disorders.

I was awarded a Fellowship of the College of Speech Therapists in the same year and a decade later (1993) was honoured with an MBE for services to speech and language therapy. I was awarded a doctor of science by the University of the West of England in 2000.

I was Chair of the Royal College of Speech and Language Therapists (1994) and served on many College committees over the last 20 years. I have been serving on the board again since 2014. I have been President of the Community Rehabilitation Team Network since its inception in 1996 and have served as the President of the Society for Research in Rehabilitation (1994 to 1996) following serving on many council committees associated with this interdisciplinary research Society. I have been that a member of the IALP for 25 years and currently I am president elect.

I was given life membership to the British Society of Rehabilitation Medicine in recognition of my contribution. I have assisted the Department of Health on several working groups related to guideline, policy and strategy development. I was Clinical Director of the South Yorkshire Comprehensive Local Research Network from 2008 to 2011. I have been chair of South Yorkshire HealthWatch between 2011 and 2014.

Dr Rosemarie Hayhow, MSc, PhD, FRCSLT

Honorary researcher BSLTRU

Rosemarie qualified as a SLT in 1969 and worked with a varied caseload until the completion of her Masters in 1975 (University of London). She specialised in stammering working mainly with adults, teaching undergraduates and undertaking treatment evaluation research.  She obtained a Diploma in Personal Construct Psychology in 1989 and included children in her clinical work.  

Rosemarie moved to Bristol in 1995 to a clinical post with children and adults who stammer. She studied the Lidcombe Program in Australia and was seconded to a stammering research study at BSLTRU in the late 1990s. Her PhD study (University of the West of England, 2009) focused on parents’ experiences of the Lidcombe Program and she was awarded a Fellowship of the RCSLT for her work in stammering.

Rosemarie is an advisor for both the British Stammering Association and the RCSLT and a founder member of the Lidcombe Program Trainers’ Consortium.  She is an occasional reviewer for academic journals.  The research topics have mainly developed from clinical questions and been influenced by an interest in personal meanings and experiences and by the variations in responsiveness to treatment that are evident in clinical work. She has worked with members of the ALSPAC team investigating outcomes for children who stammer.

Hannah Lane

I studied Speech and Language Therapy at Birmingham City University and graduated in 2016. I work as a paediatric Speech and Language Therapist for Doncaster and Bassetlaw Hospitals NHS trust. I work in the community and my role is split across community clinics, a severe learning disability school and pyramids of mainstream schools. I am also the Cleft Lip and Palate LINK therapist so am responsible for the management and therapy for a caseload of children with Cleft Lip and Palate and an important part of my job is liaising with regional Cleft hubs and specialists.

My work with the Unit was a project which formed part of my internship with the National institute of Health Research which will took place over 6 months in 2017-2018. The project explored the impact of early intervention on speech in children born with cleft palate. This is an area of significant interest to me and I am hoping to contribute to the growing evidence-base for children with speech difficulties.

Mrs Sarah Overton, MA (Hons), BSc (Hons)

Speech and Language Therapist

I qualified as a Speech and Language Therapist at Newcastle University in 2008 and have been working with children and young people ever since.

During my year as a Research Assistant at BSLTRU I worked part-time on a study with Dr Yvonne Wren exploring the potential use of language transcription and analysis software for outcome measurement. The study explored whether it was feasible and reliable for an Assistant Speech and Language Therapist to carry out language transcription as a way of surmounting the time constraints that prevent Speech and Language Therapists from routinely transcribing language samples themselves. Our research was presented at the Child Language Seminar (Newcastle University, 2012) and published in Child Language Teaching and Therapy (2014).

Mrs Jennifer Short, BSc (Hons) Speech Sciences

Specialist Speech and Language Therapist

I qualified as a speech and language therapist from UCL, London in 2002 and after a stint in the Outer Hebrides in a broad generalist post I specialised with adults with acquired and progressive neurological conditions. I have worked most of the rest of my career in Bristol and have also developed a specialism in working with  adults who stammer, currently co-chairing the South West Disorders of Fluency CEN. Although my first love in my clinical career was in acquired aphasia, I have seen an increasing number of clients referred with ‘psychogenic’ or ‘functional’ dysphagia or communication problems, and have become aware of the lack of research and evidence-based practice guidelines for this client group.
