Biography
I completed my PhD in Health Psychology at University College London in 2017, with a thesis focused on the development and evaluation of a theory-based smartphone app to reduce alcohol consumption.
After completing my PhD, I worked as a Research Fellow (2017-2020) and subsequently as a Senior Research Fellow (2020-2023) in the UCL Tobacco and Alcohol Research Group. Over this time, I was successful in obtaining competitive funding as demonstrated by three grants as Principal or Co-Principal Investigator totalling over £1.1 million. This work involved updating and refining the alcohol reduction apps, and a large-scale randomised controlled trial to evaluate its effectiveness and cost-effectiveness. In 2022, I received the Fred Yates Prize from the Society for the Study of Addiction for Researcher of the Year for a significant contribution in the field of addiction research in recognition of this work.
In 2023, I was awarded a 5-year NIHR Advanced Fellowship to work on “Alcohol harm reduction in at-risk drinkers in the UK: a mixed-methods approach to increase the number and success of reduction attempts made” at the University of Bristol within the School of Psychological Sciences and the Tobacco and Alcohol Research Group.
Research interests
I am a Senior Research Fellow in the School of Psychological Science on a prestigious 5-year Fellowship from the National Institute for Health and Care Research. My research focuses on alcohol harm reduction and the use of digital interventions, and is underpinned by behavioural science and theory.
A major focus of my research is on digital interventions to reduce hazardous and harmful alcohol consumption. As part of my research, I led the development and evaluation of a theory- and evidence-based smartphone application – Drink Less – to reduce alcohol consumption. The Drink Less app is one of the leading alcohol reduction apps in the UK with over 90,000 unique users and an average 4.6 star rating in the App Store. I was awarded the Fred Yates Prize for Researcher of the Year by the Society for the Study of Addiction in 2022 in recognition of this significant contribution and clear dedication to the field of addiction research.
I have had sustained success in securing competitive funding across eight research awards (over £6 million), with five of these as PI or co-PI and have a strong publication record with over 71 peer-reviewed papers.
My strong national and growing international profile is evidenced by regular invitations to speak and well-established international research collaborations. I make sustained expert contributions to the media, disseminating my research to the public. I am an Associate Editor at the journal Addiction, and regularly participate in peer-review for journals, conferences and grants (e.g., European Research Council).
Throughout my research, I follow the principles of Open Science, such as sharing anonymised datasets, relevant materials, source code, data and results through online repositories.
