Research Summary

The mission of the Computational Cardiology Lab is to develop and exploit cutting-edge computational tools to advance the understanding of the fundamental mechanisms that underlie rhythm and contractile disorders in the heart and to develop better strategies for prevention and treatment of these disorders. The research in Dr. Trayanova’s Computational Cardiology Lab centers around understanding the normal and pathological electrophysiological and electromechanical behavior of the heart using multi-scale simulation approaches that include biophysically-detailed representations of cellular and subcellular processes and image-based descriptions of the geometry and structure of the heart. Research projects focus on the mechanisms for cardiac arrhythmogenesis and cardiac electromechanical interactions. Importantly, a large number of projects are devoted to the improvement of the clinical therapies of defibrillation, infarct-related ventricular ablation, and cardiac resynchronization therapy using a personalized approach. Research in Dr. Trayanova’s laboratory is supported by grants from NIH, NSF, and the American Heart Association.
