Additionally he completed an echocardiography fellowship at Instituto de Cardiologia do Rio Grande do Sul, where he is currently completing a MSc.

His main research interests include cardio-oncology and structural heart disease. He is finishing an advanced echocardiography fellowship at McMaster University. Filipe is working on cardio-oncology research projects under the mentorship of Darryl Leong, including on the studies RADICAL-PC and SCHOLAR-2, and doing systematic reviews on prostate cancer risk factors and survivorship/CV outcomes.

Harry Klimis

Research Fellow

Harry Klimis is a Clinical and Research Fellow at PHRI and McMaster University, supervised by Darryl Leong and Salim Yusuf. His training features an integrated cardio-oncology research and clinical program dedicated to understanding the evolution of cardiovascular risk factor patterns in healthy populations and people with cancer, and their association with CVD and mortality. Harry is an investigator in the RADICAL-PC and SCHOLAR-2 studies, and will be working on the PURE study.

Harry is an Australian cardiologist and completed both his MBBS and PhD at the University of Sydney. His research has primarily focused on primary prevention of cardiovascular disease and digital health interventions. Other research interests include cardio-oncology and echocardiography.

Deborah Siegal

Associate Scientist

Deborah Siegal is an Associate Professor in the Department of Medicine within the Division of Hematology at the University of Ottawa. Her primary research interests include improving patient outcomes after anticoagulant-related bleeding; management of anticoagulants in patients who have acute bleeding complications or require urgent surgery; understanding the factors that influence patient and physician decision-making after anticoagulant-related bleeding; and reducing red blood cell transfusion by minimizing iatrogenic blood loss for laboratory testing.

With expertise in the design and conduct of pragmatic cluster randomized trials, individual patient randomized trials, mixed-methods studies, observational studies and meta-analyses, Deborah Siegal has received peer-reviewed grant support as principal investigator from the Canadian Institutes of Health Research, the American Society of Hematology, CanVECTOR/Heart and Stroke Foundation of Canada, Ontario AFP Innovation Fund, and Hamilton Health Sciences Foundation. She has published 70 peer-reviewed articles including several in high-impact journals such as The New England Journal of Medicine, Circulation, Blood, and Journal of Thrombosis and Haemostasis.
