Natalia Trayanova is a biomedical engineer who pioneered the use of 3D virtual heart models that are personalized using data from individual patients with ventricular or atrial fibrillation, two types of irregular heartbeats. Using these heart replicas, Trayanova and her clinical collaborators can predict who is at risk for sudden death or stroke, as well as determine the optimal patient-specific treatments for these disorders.

In 2019, Trayanova was inducted into the Women in Technology International Hall of Fame, an award established 25 years ago to recognize outstanding contributions women have been making in technology and innovation.

By leveraging innovations in cardiac imaging, computer simulations, and data science, Trayanova's research is aimed at eliminating much of the guesswork involved in the diagnosis of cardiac disease, simplifying the lengthy and invasive cardiac mapping process, reducing the complications associated with treatment, and improving patient outcomes.
