Rebecca Gladdy
Rebecca Gladdy Rebecca Gladdy is a surgeon-scientist and surgical oncologist who joined the Division of General Surgery at Mount Sinai Hospital, Toronto in July 2009. Her scientific and clinical interests are in the area of sarcoma. Rebecca is a graduate of the medical school at Queen's University, and obtained her general surgery training at the University of Toronto, graduating from our program in 2005. She is also a graduate of the Surgeon Scientist Training Program at the University of Toronto, and obtained her PhD in 2003, under the supervision of Jayne Danska and Cindy Guidos. Her doctoral studies focused on the early genetic changes in leukemia, including how different molecular signatures influenced the behaviour of leukemic stem cells. Following her general surgery training, she completed a brief period of postdoctoral research at the Lunenfeld Institute at Mount Sinai Hospital, assessing cytogenetic characteristics of malignant cells haploinsufficient for the tumour suppressor polo-like kinase 4. Rebecca then completed a two-year fellowship in surgical oncology at Memorial Sloan-Kettering Cancer Center in New York, where her interest in sarcoma as a research and clinical focus emerged. Her research work while at MSKCC included studies of radiation associated sarcoma and the natural history of leiomyosarcoma. In addition, she completed additional postdoctoral training to acquire techniques to establish mouse models of sarcoma, and formed ongoing collaborations with basic scientists in New York. Upon joining the faculty of the Department of Surgery here at the University of Toronto as an Assistant Professor, Rebecca successfully competed for a substantial award as a Clinician Scientist in the Selected Therapies Program of the Ontario Institute for Cancer Research and obtained a career development fellowship from the American Surgical Association. She has already established an independent laboratory as an Associate Scientist at the Lunenfeld Institute, and is developing a Functional Genomics program with the goals of defining which molecular signatures of sarcoma can be utilized for the development of novel therapies.
