Dr Gzell has completed undergraduate degrees in both Medical Science (University of Sydney, 1998) and Medicine (University of Newcastle, 2003). She undertook Radiation Oncology Specialist training primarily at Royal Prince Alfred Hospital (2006-2011) prior to becoming a fellow of the Royal Australian and New Zealand College of Radiologists (Faculty of Radiation Oncology) in 2011. Between 2012-2014 she undertook a post-graduate fellowship in Neuro-Oncology at Royal North Shore Hospital with research and publications in the field of high-grade gliomas. This research formed the basis for a PhD thesis entitled: Optimising outcomes in patients with glioblastoma receiving radiotherapy (conferred 2017).

In 2014 Dr Gzell joined Genesis Cancer Care and works as a Radiation Oncologist at St Vincents, the Mater, and Macquarie University Hospitals. She has Honorary appointments at these hospitals as well as Concord General Repatriation Hospital.

Dr Gzell has been involved with the Co-operative Trials Group for Neuro-Oncology (COGNO) since becoming a member in 2011. In 2014 she was on the Annual Scientific Meeting (ASM) Organising committee and was the Convenor of the ASM in 2015. In 2016 she was the Co-Convenor of the combined COGNO-ASNO (Asian Society of Neuro-Oncology) ASM and Chair of the Stereotactic Radiosurgery Workshop. She was appointed to the COGNO Management Committee in 2016. Dr Gzell is a full member of the Society of Neuro-Oncology (SNO, USA).

Her main focus is the best management of both primary and secondary central nervous system neoplasms utilising modern techniques including stereotactic radiosurgery and gamma knife surgery. She aims to increase patient access to clinical trials for brain tumours at St Vincents’ campus.
