Research Overview

As we go down in size, there are a number of interesting problems that arise. All things do not simply scale down in proportion.

There's Plenty of Room at the Bottom, Richard P. Feynman, 1959

A time-honored objective in engineering sciences is the theoretical and computational understanding of multiscale problems. As the world moves towards sustainability, multiscale computational modeling can greatly accelerate scientific research and industrial productions, e.g., faster drug discovery, efficient battery design, novel energy sources exploration, and systems and materials design. My research goal is to develop computational methods to better model and simulate multiscale engineering phenomena that can bring good for mechanical, materials, and systems design with practical applications in energy, bioengineering, and manufacturing. My research briefly focuses on the following three aspects, combined with selected works.
