Dr. Marcus completed his internship, residency, and served as Chief Resident in internal medicine at Stanford before coming to UCSF for his general cardiology and electrophysiology fellowships. As part of an NIH-funded career development award as a junior faculty member, he also completed a Master’s in Advanced Studies in Clinical Research at UCSF. In addition to having an active clinical practice in cardiac electrophysiology implanting pacemakers and defibrillators and performing catheter ablations, Dr. Marcus also oversees multiple research projects funded by the NIH and industry partners and is the research mentor for many of the cardiovascular trainees at UCSF. Along with Co-PIs Drs. Jeffrey Olgin and Mark Pletcher, he conceived and has overseen the development of the Health eHeart Study, now a global, nimble, internet-based cardiovascular study with multiple capabilities that leverage technology. The study has become a research platform used by collaborators across the nation representing multiple fields in medicine. In addition to enabling efficient, geographically unrestricted, and convenient participation, the study is also designed to seamlessly integrate with multiple sensors and mobile apps and devices, providing the framework for the rigorous study of new technologies in a cost-effective fashion.
