Dr. Ali received his MSc and PhD in Medical Physics from Carleton University. He then joined The Ottawa Hospital Cancer Centre for a two-year residency in radiation Oncology Physics, and transitioned into a staff medical physicist in 2015. He is a member of the Canadian College of Physicist in Medicine (MCCPM) and holds academic appointments as an Assistant Professor at the Department of Radiology, University of Ottawa, and as an Adjunct Research Professor at the Department of Physics, Carleton University. He is a member of the Carleton Laboratory for Radiotherapy Physics (CLRP, http://www.physics.carleton.ca/clrp) and a Clinician Investigator with the Ottawa Hospital Research Institute (OHRI).


Current research: (a) Development and validation of different rapid-access palliative radiation therapy models. (b) Developments in cone beam CT for better geometric patient positioning, reduced imaging dose, and cone-beam-based radiation treatment planning. (c) Accurate dosimetric markers for radiation-induced early symptoms. (d) Auto-segmentation of the bowel bag using mathematical modelling and/or machine- and deep-learning methods. (e) Development and validation of Monte Carlo radiation transport methods for radiation measurements and dose calculations. This research is carried out primarily at The Ottawa Hospital Cancer Centre, with collaborators at Carleton University, the National Research Council Canada, and at Le Laboratoire TIMC-IMAG in France. Dr. Ali’s research group includes radiation oncology physics residents, graduate students at the MSc and PhD levels, as well as undergraduate and coop students. He served as a member of Task Group 195 of the American Association of Physicists in Medicine (AAPM) on Monte Carlo reference datasets for imaging research, and he is currently a member of the AAPM Working Group for Imaging in Treatment Planning.
