Dr. Alexandra Rink is a Senior Medical Physicist at the Princess Margaret Cancer Centre, an Associate Professor in the Department of Radiation Oncology and Department of Medical Biophysics, University of Toronto and a Clinician Scientist at the Princess Margaret Research Institute.

She received her B.Sc. degree with honours in Chemical Physics from the College of Physical & Engineering Science at University of Guelph in 2003, and thereafter pursued a PhD in the Department of Medical Biophysics at the University of Toronto. Her thesis, supported by the National Cancer Institute of Canada through a Terry Fox Foundation Research Studentship Award, focused on using polymer materials and optical fibre read-out in order to measure radiation dose remotely during the application of radiotherapy.

Upon completion of graduate studies in 2008, Dr. Rink had commenced a Medical Physics Residency program at Princess Margaret Cancer Centre with the Department of Radiation Oncology, University of Toronto. In 2010, Dr. Rink joined the Image-Guided Interventional Radiotherapeutics for Prostate Cancer group as a Clinical Physics Fellow and in 2012 the Radiation Physics department as staff. She has been leading the brachytherapy physics group at the Princess Margaret Cancer Centre since 2013.

Dr. Rink has started her own lab in 2019, with research interest in quality improvement of brachytherapy and post-treatment quality of life through dosimetric measurements using in-vivo optical fibre technology, implant accuracy and efficiency through automation.
