Julian Treadwell


Honorary Research Fellow and General Practitioner

I completed my DPhil in August 2023 via an NIHR Doctoral Research Fellowship under the supervision of Prof. Trisha Greenhalgh and Prof. Kamal Mahtani.

My doctoral research led to the production of a website,, which delivers information to General Practitioners and other healthcare professionals about the benefits and harms of treatments for common long-term condtions. This aims to support shared decision making in clinical practice, particularly in contexts of multimorbidity and polypharmacy.

The website was developed using qualitative and participatory co-design methods to develop novel ways to communicate complex information. It is currently freely available and hosted at the Nuffield department of Primary Care Health Sciences.

My research interests include multi-morbidity and polypharmacy, the role of clincal guidlenes in practice, and overdiagnosis and over-treatment.

I have additional  roles as a co-moderator of the NICE GP Reference Panel and as an associate editor of the Drug and Therapeutics Bulletin. I co-founded and was Vice-Chair of the RCGP standing group on Overdiagnosis from 2014-18.

My clinical work is based in Oxford.
