I am a cardiac electrophysiologist with a faculty appointment as Assistant Professor of Medicine in the Division of Cardiovascular Medicine at the University of Toledo College of Medicine and Life Sciences. After completing medical education at Christian Medical College, Vellore- India, I pursued residency training at Drexel University College of Medicine and advanced fellowships in Cardiac CT/MRI at The Ohio State University, Cardiovascular Disease at Case Western Reserve University/MetroHealth Medical Center, and Clinical Cardiac Electrophysiology at Mayo Clinic. Since joining the University of Toledo in 2020, I developed a comprehensive electrophysiology practice while serving as Director of the Electrophysiology Laboratory, where I lead program development, quality initiatives, and procedural innovation.
My academic interests center on advancing the treatment of cardiac arrhythmias through research, education, and clinical leadership. My interests focuses on atrial fibrillation, ventricular arrhythmias, catheter ablation, cardiac implantable electronic devices, and outcomes research using large-scale clinical datasets, systematic reviews, and multicenter collaborations. Besides being a clinician, I teach medical students, residents, fellows, and allied health professionals through classroom instruction, procedural training, and clinical mentorship, with an emphasis on physiology-based clinical reasoning and evidence-based patient care.
My focus is to deliver world calss care to patients in Toledo and around North East Ohio without the need for patients to travel elsewhere.
