Dr McDonald has both a private and an NHS practice at The Royal Marsden. She is a Consultant Clinical Oncologist specialising in the treatment of patients with lung cancer.

Dr McDonald studied medical sciences at Cambridge University and was awarded a first-class BA (Hons) degree in 1994. She subsequently qualified from Barts and The London School of Medicine in 1997. After general medical training at St. Mary’s Hospital, she completed her specialist oncology training at The Royal Marsden and Guy's and St. Thomas’ Hospitals. She was awarded the Frank Doyle Medal from the Royal College of Radiologists in 2002.

She was awarded the president's prize for her research degree at The Institute of Cancer Research between 2008 and 2012 in individualised image-guided adaptive radiotherapy techniques for lung and bladder tumours, including implementation of lung stereotactic radiotherapy for early stage and oligometastatic lung tumours in 2009. She was subsequently appointed as a Consultant Clinical Oncologist at The Royal Marsden in 2012.

Dr McDonald's research aims to improve outcomes by developing individualised approaches to lung radiotherapy through integration of novel functional imaging and targeted biological agents with advanced radiotherapy technologies, including stereotactic/CyberKnife radiotherapy, intensity-modulated and image-guided adaptive radiotherapy. She is the clinical lead for novel developmental work on Magnetic Resonance (MR) guided adaptive radiotherapy for lung tumours.
