About me

  • Assistant Professor of Clinical Medicine (Cardiovascular Medicine)

I am originally from Curitiba, Brazil, where I earned my medical degree in 2007 from the Federal University of Paraná, the oldest University in the country. After practicing a few years as a Family Physician in my hometown, I moved to the United States in 2009 to work as a post-doctoral research fellow in Biophysics at the Armed Forces Institute of Pathology, in Washington, D.C. I then completed my Internal Medicine residency, followed by a year as a Chief Resident, at the Georgetown University Hospital/Washington Hospital Center program, the largest hospital in our nation's capital. My Cardiology fellowship was then completed in New York, at NYU School of Medicine. Since 2018, I have been at Penn Medicine, where I received my training in cardiac electrophysiology and stayed as an attending physician treating patients with cardiac rhythm disorders.
