I am currently working as a research fellow on the ROSETA trial, which involves developing, adapting and optimising four behavioural interventions (SMS messages, information leaflet, acceptance and commitment therapy, side-effect management website) to support medication adherence in women with breast cancer. This work is guided by the Multiphase Optimisation Trial (MOST); a framework that can be used to optimise complex behavioural interventions. 

I am also currently completing my PhD in intervention development and optimisation (supervised by Dr Samuel Smith, Dr Louise Hall, Dr Nikki Rousseau and Professor David French). My PhD involves four research studies using a range of methods, including:

  • Combining intervention mapping and the multiphase optimisation strategy to develop a complex behavioural intervention to support medication adherence in women with breast cancer (including three rapid reviews)
  • A series of survey and focus group studies to develop a pool of text messages to support habit formation for medication taking in women with breast cancer
  • A factorial screening experiment to optimise an information leaflet to increase necessity beliefs and reduce concerns in women with breast cancer
  • A mixed-methods process evaluation of a pilot trial to investigate acceptability of four intervention components designed to support medication adherence in women with breast cancer

In 2022 I was awarded a Health Behaviour International Collaborative Award, sponsored by the International Behavioural Trials Network. This work will explore decision making in intervention optimisation when there are multiple outcomes of interest, applied to the information leaflet developed as part of my PhD. Professor Linda Collins is the mentor on this award. I am additionally the current events officer for the UK Society of Behavioural Medicine Early Career Network. 

My background is in Psychology. I graduated from Durham University in 2018 with a BSc in Psychology and King's College London in 2019 with an MSc in Mental Health Studies. I then completed clinical training as a Psychological Wellbeing Practitioner (2019-2020), obtaining a Postgraduate Certificate in Low Intensity Cognitive Behavioural Interventions at University College London (UCL).
