Dr Chantelle Rizan (BSc (Hons) MBBCh MRes MRCS (ENT) PhD)

Clinical Lecturer

Area of expertise: Sustainable Healthcare, Quality Improvement, Human and Planetary Health

Research areas: Sustainable Surgery

Other relevant positions: ENT Research Fellow, University Hospitals Sussex NHS Foundation Trust, Surgical Research Fellow, Royal College of Surgeons of England
Sustainable Surgery Fellow, Centre for Sustainable Healthcare


Chantelle was appointed as Clinical Lecturer in Sustainable Healthcare at Brighton and Sussex Medical School in 2022, following her PhD evaluating ways to mitigate the carbon footprint of products used in the operating theatre. Chantelle seeks to translate her research into practice and policy, and is an academic advisor for a national report on Greener Surgery in collaboration with UK Health and Climate Change Alliance. Key achievements include receiving the Hillary International Health and Care Leadership Award (2022), and the Adam Weiler Doctoral Impact Award (2021) for outstanding academic impact. 


Chantelle’s research aims to provide an evidence-based approach to improve the sustainability of healthcare, with a particular focus on mitigating carbon footprint associated with products used for surgical products. She uses carbon footprinting and life cycle assessment methods to identify carbon hotspots, to evaluate the environmental impact of alternative products, and to optimise associated processes.


Chantelle teaches on topics related to sustainable healthcare on both undergraduate and postgraduate courses at BSMS. Chantelle regularly delivers teaching on sustainability to healthcare professionals from a range of clinical backgrounds, through workshops at the Centre for Sustainable Healthcare, and within national and international webinars and conferences.
