Research Interests

Igor Efimov’s Research Interests: My Cardiovascular Engineering laboratory focuses on the physiological mechanisms of cardiovascular disease and on developing novel therapies for heart diseases with an emphasis on heart rhythm disorders and heart failure. Two engineering strategies are pursued: (1) development of novel implantable, interventional, and wearable bioelectronic devices for real-time device-based diagnostics and therapy of heart diseases and sudden cardiac death; (2) development of novel approaches to bioinformatics and machine learning to diagnose early stages or predisposition to heart disease and to guide the development of novel therapies.
