My research involves optimizing radiotherapy planning and delivery to maximize organ-at-risk (OAR) sparing with the goal of improving the quality of life of cancer patients.  Currently, this involves determining automated ways to choose radiation beam placements to avoid entrance dose to the OARs. These methods are commonly called 4pi techniques in the literature as they search the 4pi sphere of space around the patient to determine the optimal beam placements. My team have developed a number of algorithms to aid in this, and this work has been licensed by Brainlab, a radiotherapy and surgical device company, and is now in radiotherapy clinics worldwide.

What brought you to your current institution? After doing my graduate and post-graduate studies in Ontario and working in the US, I decided it was time to move back to Nova Scotia to be close to my parents.  I was offered a position at the Nova Scotia Health Authority and with the increased focus on research in the Medical Physics department presenting a unique opportunity, I accepted the offer.
