Research Interests:

Dr. Toma’s research interests include outcomes research in heart failure, heart transplantation and mechanical circulatory support. He also has an active interest in biomarkers research and he has been involved with the PROOF Centre of Excellence for the Prevention of Organ Failures working on identifying biomarker panels for the diagnosis and prediction of numerous processes as they relate to acute and chronic heart failure, as well as cardiac transplantation.
