Beverley Nickolls


PhD Research Student



I gained a degree and Masters in English Language and Literature from St Anne’s Oxford in 1991. I first worked as a Hearing Therapist/Audiologist in the NHS including coordinating the training courses at the City Lit London and subsequently at the University of Bristol. Since, I have worked in a variety of health and community settings including as the ‘Bump to Baby’ Family Support Worker for a first wave Surestart Children’s Centre and Coordinator of Breastfeeding Peer Supporters in the local community as part of a North Somerset research project. I am also trained as a CAM practitioner. Alongside my professional roles, I have undertaken a range of research-based postgraduate training including via the School of Health and Related Research (ScHARR).  


Research Interests:

The title of my PhD is ‘The Staged Approach to Informed Consent in Trials within Cohorts (TwiCs): Experiences, Methodological Approaches and Insights’. I am interested in how to design trials that are more relevant, salient and inclusive for patient stakeholders and representative of the populations they serve. My methodological interests are in innovative recruitment and informed consent processes and embedding clinical research into routine care. I am currently working on a scoping review of trials using cohorts and has an interest in the Trials within Cohorts (TwiCs) design ( as a means to create ‘learning health systems’.
