Sanjiv Narayan, MSc, MB, MD, FRCP


Dr. Narayan is Professor of Medicine at Stanford University, a practicing cardiologist and translational scientist with graduate training in software engineering and neurophysiology. Dr. Narayan directs Electrophysiology Research at Stanford, and has built an independently funded “bedside-to-bench-to-bedside” translational research program focused on mechanisms for human AF and life-threatening ventricular arrhythmias. This work led to the development of novel mapping for fibrillation, the discovery of rotors in human AF, with ablation (Focal Impulse and Rotor Modulation, FIRM) as the basis for novel therapy at AF and VF rotors. The laboratory is grateful for funding of this work by the National Institutes of Health from 2001-2019 (K23 HL70529, R01 HL83359, K24 HL103800, R01 HL122384, SBIR), and also by the Doris Duke Charitable Foundation, American College of Cardiology and American Heart Association.  Dr. Narayan is Associate Editor of the Journal of the American College of Cardiology (JACC), and of JACC: Clinical Electrophysiology.

Dr. Narayan is active in mentorship, and has trained numerous graduate students in bioengineering, residents and fellows in training, medical and undergraduate students. In addition to presenting and publishing their work, many trainees have received extramural funding from AHA, ACC, HRS, BHF and other agencies, have won research and clinical prizes and over 80% remain in academic medicine. Dr. Narayan has won teaching prizes for his mentorship, and his mentored training program in patient-oriented research was just renewed by NIH for a second permissible funding period (NIH K24 HL103800). He serves as Vice-Chair of the Fellowship committee of the Heart Rhythm Society (2012-present).

Dr. Narayan was born in Aylesbury, Buckinghamshire, England, then his family moved to Birmingham where he trained in medicine then in software engineering (MSc, 1st prize), becoming a fellow of the Royal College of Physicians of London (FRCP). He then did his doctoral research in neuroscience at the University of California Los Angeles.  His clinical training in Internal medicine was then continued at Harvard/Mount Auburn Hospital, then in Cardiology/EP at Washington University in St. Louis. Dr. Narayan is board-certified in Internal Medicine, Cardiology and Clinical Cardiac Electrophysiology, has been voted as a “Top Doctor”, and has an active clinical practice at Stanford. He is a devoted family man, and he and his wife have three children. Together, they enjoy swimming, biking, skateboarding (selected members of the family), music and travel.

Tina Baykaner, MD


Dr Baykaner is a clinical Electrophysiology fellow at Stanford University. She obtained her medical degree from Hacettepe Universitesi, Ankara, Turkey. During medical school, she spent 6 months in genetics and endocrine labs at the NIH/NICHD, followed by clinical cardiology rotations at the Cleveland Clinic and Baylor University which influenced her to pursue postgraduate training in the United States. After obtaining her MD, she spent a year at the Massachusetts General Hospital in Boston, MA as a postdoctoral fellow researching determinants of ischemic stroke evolution. She then started her clinical training in Internal Medicine at AECOM/Jacobi Medical Center in New York and continued her training at University of California San Diego which included residency Internal Medicine, fellowships in Advanced Heart Failure and Clinical Cardiology. During her clinical training, she obtained an online MPH degree from University of Massachusetts to further her knowledge in statistics and outcomes research. Starting in early years of her clinical residency training, she started working with Sanjiv Narayan on mechanisms of atrial fibrillation. This research has yielded her multiple recognitions including University of California San Diego Schulman Early Career Research Award in Cardiology, American Heart Association Post-Doctoral Research Fellowship Grant, Heart Rhythm Society Research Fellowship Scholarship in Honor of Mark Josephson and Hein Wellens, Travel Scholarship from American College of Cardiology as well as multiple featured poster and oral presentations in national and international meetings. She will continues her ongoing research projects in AF mechanisms with Dr Sanjiv Narayan while pursuing a 2 year clinical electrophysiology training at Stanford University.  When Tina is not in the lab, she can be found playing tennis, away for skiing, enjoying a beach run or discovering new restaurants.

A.J. Rogers, MD, MBA


Dr. A.J. Rogers is a Electrophysiology Fellow at Stanford University. He has over 10 years of medical device experience ranging from basic and translational research to device development and entrepreneurship. His undergraduate coursework in Biomedical Engineering at Duke University focused on neurobiology, signal processing, and computer modeling while his research investigated piezoelectric arrays for intracardiac ultrasound and computer vision of 3D ultrasound images for automated surgical robot tasks (Stephen Smith Laboratory). He earned his medical degree from the University of North Carolina and graduated in the inaugural class for the combined MBA degree program from the Kenan-Flagler Business School at UNC (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 company in the field of heart failure. He completed training in Internal Medicine and Cardiovascular Medicine at Stanford University. He joined Dr. Sanjiv Narayan’s Computational Arrhythmia Research Laboratory to explore mechanisms of cardiac fibrillation using techniques of 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.
