Xiaopeng Zhao, an assistant professor in the Department of Mechanical, Aerospace and Biomedical Engineering, recently received a National Science Foundation CAREER award for a project entitled “Integrated Research and Education in Nonlinear Dynamics in Biological Systems.” The goal of his project is to develop a framework for understanding the dynamics of heart rhythm disorders that lead to fatal cardiac diseases such as ventricular fibrillation and atrial fibrillation. This research could have a profound impact on human health worldwide; in the United States alone, sudden cardiac death kills more than 350,000 people every year. In addition, Zhao’s research will support new cross-disciplinary collaborations in the areas of biomedical engineering, life science, and mathematics.
Zhao earned his Ph.D. at Virginia Tech and joined UTK in 2007. Since then he has been conducting research in the areas of computational cardiology, mathematical physiology, nonlinear dynamics in biology and medicine, and system biology.
