Short Bio
Catherine Coolens is an Associate Professor at the University of Toronto, Department of Radiation Oncology and a Staff Medical Physicist in the Radiation Medicine Program at Princess Margaret Cancer Centre – University Health Network. She received her PhD in Medical Radiation Physics under Steve Webb at the Institute of Cancer Research, University of London working on Intensity-Modulated Radiation Therapy optimization. She consequently obtained her board-certification and worked at the Royal Marsden Hospital in London (UK) where she worked on organ-motion tracking and gated imaging and therapy techniques. In 2008 she was recruited to Toronto where she started her own lab.
Research Synopsis
At Princess Margaret Cancer Centre, Dr. Coolens and her team work on three main topics:
- Development and validation of functional imaging techniques for imaging of tumor micro-vascularity and radiation therapy response. This has been successful in dynamic contrast-enhanced (DCE) CT and MRI and is being further investigated for metabolic imaging using PET-MRI. The validation of these techniques in done in silico as well as through development of functional testing frameworks and 3D-printed biological phantoms.
- Pharmaco-kinetic and fluid dynamic modeling of solute transport to probe the tumor microenvironment and assess biological features such as tumor hypoxia and efficacy of drug delivery. This spans use of contrast agents for quantitative imaging as well as larger weight molecules used in immunotherapy and nanoparticle-based therapeutics.
- Clinical trials, focused on CNS and liver where the above techniques can be assessed for their prognostic ability to personalize cancer treatment and elucidate best management strategies based on early response assessment and tumor control evaluation.
