Research Worker


I am the patient and public involvement (PPI) research coordinator for King’s Improvement Science and a service user researcher, having joined the team in September 2018.  

I co-lead on the PPI strategy within the Centre for Implementation Science & King’s Improvement Science, and work closely alongside the Service User Research Enterprise (SURE). I also work as an independent reviewer for the National Institute of Health Research (NIHR) and continue my service user involvement on research project advisory panels with the McPin Foundation.  

Coming from a multidisciplinary background, I trained in the digital humanities gaining an MSc from Southampton University, where I looked at novel ways of utilising digital technology to aid collaborative learning with museum artefacts. After working as a database analyst and programmer for the Medical Research Council Lifecourse Epidemiology Unit, I went on to work as a peer researcher and peer support worker, utilising my lived experience of mental health, before moving into the field of patient and public involvement at King’s.
