## Educational Background

**PhD**, Applied and Computational Mathematics, (Mathematical Biology), University of South Carolina, 2015 Dissertation

## Biography

Dr. Zhao is an applied and computational mathematician with a keen interest in interdisciplinary research, aiming to strike a balance among mathematical modeling, numerical analysis, and high-performance computations. His research is highly interdisciplinary, residing at the interface between applied mathematics, scientific computing, soft matter physics, and mathematical biology. His current research projects include numerical analysis of thermodynamically consistent hydrodynamic models, modeling and computation of multiphase complex fluids and complex biological systems (biofilms, cell motility, and liquid-liquid phase separation in intracellular dynamics). Dr. Zhao's research has been supported by the National Science Foundation (NSF), National Institutes of Health (NIH) and AMS-Simons Travel Award from the Simons Foundation.
