A composite image of the Wall Street Journal masthead and elements of a news story about digital twins, including a heart model and a photo of Natalia Trayanova.

“In a Baltimore lab, Natalia Trayanova and her team at Johns Hopkins University are creating computational models of hearts. Each one mirrors the heart of a real patient with a potentially fatal arrhythmia, an irregular heartbeat that is often a result of scarring from heart attacks or other conditions.”

Read Stephanie Armour’s story, “A ‘Digital Twin’ of Your Heart Lets Doctors Test Treatments Before Surgery” in the May 16 issue.

Trayanova is the Murray B. Sachs Professor in the Department of Biomedical Engineering and a professor of medicine at the Johns Hopkins School of Medicine. She directs the Alliance for Cardiovascular Diagnostic and Treatment Innovation, a research institute with faculty from medicine, biomedical engineering, radiology, and applied math, aimed at applying predictive data-driven approaches, computational modeling, and innovations in cardiac imaging to the diagnosis and treatment of cardiovascular disease.

She is also a member of the Institute for Computational Medicine and leads the Computational Cardiology Laboratory. She is the first female faculty member to hold an endowed professorship in the Whiting School of Engineering at Johns Hopkins University.
