Electrophysiology Fellows

AJ Rogers, MD, MBA

2nd Year

Dr. Albert (A.J.) Rogers is a Cardiac Electrophysiology Fellow and at Stanford University. He has over 10 years of medical technology research experience ranging from basic and translational research to device development and entrepreneurship. His undergraduate coursework focused in Biomedical Engineering at Duke University focused on neurobiology, signal processing, computer vision, and computational biology. He earned a combined MD and MBA from the University of North Carolina School of Medicine and the Kenan-Flagler Business School (focus in Healthcare Entrepreneurship). While working toward these degrees, A.J. participated in epidemiologic and translational research in the academic setting and worked as a clinical engineer for a start-up medical device developing an autonomic therapy for acute decompensated heart failure. He completed clinical training in Internal Medicine and Cardiovascular Medicine at Stanford University and served as Chief Cardiology Fellow. He then pursued additional research training on an NIH-funded fellowship. His research now focuses on the physiologic mechanisms of cardiac fibrillation using techniques of human signal processing, machine learning, and in silico modeling. Outside of his research and clinical pursuits, A.J. enjoys athletics of all kinds (especially sand volleyball), travelling, and live music events.


Andrew Vu, MD

2nd Year

Dr. Andrew Vu is a native of San Jose, California. He graduated from Santa Clara University with a Bachelor of Science in Chemistry, and obtained his MD degree from Creighton University in Omaha, Nebraska. He went on to complete internal medicine residency at White Memorial Medical Center in Los Angeles, California, where he also served as Chief Resident, and cardiology fellowship at California Pacific Medical Center in San Francisco, California. His research interests and publications have focused on cardiac implantable electronic device outcomes and innovation, but he enjoys all aspects of cardiac electrophysiology. He plans to pursue an academic career as a clinician-investigator in cardiac electrophysiology.


Shana Greif, MD

1st Year

Dr. Shana Greif grew up in Dobbs Ferry, New York. She graduated from Cornell University with a B.A. in psychology and obtained her M.D. from New York Medical College. She went on to complete her internal medicine residency at Kaiser Permanente Los Angeles Medical Center, where she participated in research evaluating outcomes of cryoballoon versus radiofrequency catheter ablation of atrial fibrillation. She completed her general cardiology fellowship at University of Hawaii, where she also served as Chief Cardiology Fellow and as a Clinical Faculty Instructor. During fellowship, she was involved in clinical research related to minimizing fluoroscopy use during electrophysiology procedures, including zero-fluoroscopy atrial fibrillation ablation and zero/low-fluoroscopy coronary sinus cannulation during implantation of cardiac resynchronization therapy devices. She is excited to continue her clinical and academic career as a Cardiac Electrophysiology Fellow at Stanford.


Sunil Vasireddi, MD

1st Year Year

Dr. Jeff Lin grew up near Stanford and attended Northwestern University's combined BA/MD program. He completed his internal medicine residency and a chief residency at the University of Wisconsin. His interest in electrophysiology began in medical school with his research on AF ablation outcomes. During residency, his work broadened to include device-related outcomes including the identification of predictors for CRT response and procedural aspects of CIED implantation. At Stanford, he is currently involved in projects related to AF detection and clinical characteristics of silent AF. He plans to pursue an academic career in clinical electrophysiology with a particular interest in AF and heart failure outcomes.
