Rhanderson Cardoso, MD

Dr. Rhanderson Cardoso graduated from medical school at the University of Goias in his home country Brazil. He then completed Internal Medicine residency and a chief year at the University of Miami-Jackson Memorial Hospital. Rhanderson has diverse interests in cardiovascular diseases, including electrophysiology, imaging, and prevention. He is especially passionate about teaching and hopes to have a career in academic medicine. He is currently earning a Masters degree in Cardiovascular Epidemiology at the Hopkins Bloomberg School of Public health and is planning on pursuing additional imaging training at Brigham and Women’s Hospital in the upcoming academic year.

Balint Laczay, MD

Dr. Balint Laczay is a cardiology fellow at the Cleveland Clinic Foundation. He completed his internal medicine residency at the Johns Hopkins Hospital, and prior to that completed medical school at Northwestern University. His hobbies are travel, chess, sports and trying local restaurants. He loves nerding out about cardiology and is excited about cardiac imaging, cardiac electrophysiology and medical education.

Nino Isakadze, MD

Dr. Nino Isakadze is a second year cardiovascular fellow at Johns Hopkins. She completed internal medicine residency at Emory University. Nino’s research focuses on mobile health technologies and arrhythmia detection/treatment. She is currently leading efforts in developing digital health interventions for patients with atrial fibrillation.

Weili Zheng, MD

Dr. Weili Zheng is a 3rd year resident at The Osler Medical Training Program at the Johns Hopkins Hospital. Clinically he may be a bit of a masochist, as his most fond experiences as a resident have been managing cardiogenic shock. He is also fascinated by the physiology of heart-lung interactions, and is looking into a career in Critical Care Cardiology or Interventional Cardiology. He will start as a fellow at the Cleveland Clinic this year. Outside of medicine, Weili is an avid cook and a die-hard White Sox fan (although like many native Chicagoans, he has sworn off attending games until a change in ownership occurs).

After completing his internship in Kuwait, Hamied joined the Welty Lab at Harvard Medical School as a research fellow primarily focusing on cardiovascular disease prevention research. He studied the determinants of coronary atherosclerotic plaque progression measured by coronary computed tomography angiography in patients with coronary artery disease. He then went on to complete his residency at the Beth Israel Deaconess Medical Center, where he continued to do research in cardiovascular prevention. Hamied is passionate about pursuing a career as an academic cardiologist and a physician-scientist in the field of coronary artery disease.
