Between 2008 and 2017 Phillippa took time out to be with her young family but returned to the research group at UCL for short periods to support various projects.

In 2019 Phillippa was promoted to Senior Research Fellow.

Research Summary

Phillippa's PhD and fellowship work focused on habit formation and weight control. She conducted a study tracking participants as they attempted to form a new habit and modelled the increase in automaticity over time at an individual level. This paper has been widely cited in both academic work and the media. Phillippa remains focused on habit formation and how this process can be used as a strategy to help people to change their health behaviours and maintain these changes. She has co-authored two book chapters and numerous journal articles on the psychology of habit and is co-chair of the Habit Special Interest Group of the European Health Psychology Society. Phillippa is the Trial Manager for the ASCOT Trial, and Co-PI and Trial Manager for the APPROACH Trial. Both the interventions used in these trials apply habit theory to promote health behaviour change in participants living with and beyond breast, prostate and colorectal cancer. Phillippa has also conducted research in the area of social norms for food and drink consumption, offering swaps when pre-ordering food in a workplace setting and weight loss interventions for adults with learning disabilities.
