Dr. Christopher Booth

Dr. Booth studied medicine at Queen's University before undertaking further training in internal medicine and medical oncology at the University of Toronto. His clinical interests involve gastrointestinal and genitourinary cancer. He has an active research program in population-based cancer outcomes and clinical trial methodology. Specifically, he evaluates how the findings of landmark randomized controlled trials are translated into the general population and whether the societal benefits of therapy are what one might expect based on the clinical trial results.

He is currently completing a research fellowship at the National Cancer Institute of Canada Clinical Trials Group and will begin a full-time faculty appointment within the Division of Cancer Care and Epidemiology at the Queen's Cancer Research Institute in July 2008.

Dr. Kristy Brock

Dr. Kristy Brock received her PhD from the University of Michigan, Department of Nuclear Engineering and Radiological Sciences in 2003. Her thesis work was performed at the University of Michigan Department of Radiation Oncology and focused on the inclusion of deformation in dose accumulation in liver radiotherapy. Under the supervision of Dr. James Balter, her work represents some of the pioneering work of deformable registration in the radiotherapy context. She was one of the first people to successfully apply finite element models to describe shape changes in the liver due to breathing, which were further compared to geometric approximations. This work further indicated the potential improvements in the accuracy of calculations of the accumulated dose in the presence of physiological motion through the use of deformable registration.

Following the completion of her graduate work, she joined the staff at Princess Margaret Hospital (PMH), Radiation Medicine Program and became faculty in the Department of Radiation Oncology at the University of Toronto. At PMH she leads the investigation of deformable registration and modeling for treatment planning, delivery, and response assessment. This research has shown that deformable registration can improve the integration of multi-modality images for tumor definition, the accuracy of dose estimations in the presence of physiological motion, and targeting of tumors in image-guided radiotherapy. In addition, she has developed novel applications including validation of in-vivo imaging through correlation with histo-pathology and metrics for the assessment of tumor response. Collaborations with scientists in the Ontario Cancer Institute have expanded this research to investigate the applications of deformable registration for image guided therapeutics including surgery and photodynamic therapy.

Dr. Brock serves the academic community through membership on several committees including a task group on the use of image registration and data fusion in radiotherapy through the American Association of Physicists in Medicine. She also successfully conducted the first multi-institution, international deformable registration validation study using patient images in radiotherapy. Her contribution to the field has been recognized by numerous invited presentations at international meetings.

Dr. David Hodgson

David Hodgson, MD, MPH, is an Associate Professor and clinician scientist in the Department of Radiation Oncology and the Department of Health Policy, Management and Evaluation at the University of Toronto. He is a staff radiation oncologist at the Princess Margaret Hospital, and an Adjunct Scientist at the Institute for Clinical Evaluative Sciences in Toronto. He received his medical degree and radiation oncology training at the University of Toronto, and a Masters degree in Public Health from Harvard University.

He is a member of the Outcomes and Health Services Research Committee of the American Society for Therapeutic Radiology and Oncology, a member of the U.S. Children’s Oncology Group Hodgkin Lymphoma Steering Committee and Cardiovascular Toxicity Guidelines Task Force, and has participated in health technology assessment for the Ministry of Health and Long-Term Care of Ontario, Cancer Care Ontario’s Evidence-Based Guidelines initiative, and as the Chair of the Health Services Research Network for the Canadian Association of Radiation Oncologists.

His research activities include technology assessment and the utilization of population-based health administrative data to evaluate the treatment and outcome of cancer patients at the population level. He is currently the project co-lead on a study of health care utilization among cancer survivors conducted by Cancer Care Ontario’s Patterns of Care Research Network. He has been the recipient of a Career Development Award from the Ontario Ministry of Health and Long-Term Care and is the recipient of peer-reviewed funding from the Canadian Institutes for Health Research, the National Cancer Institute of Canada and Cancer Care Ontario.
