Dr. Zhiting Tian

Assistant Professor
WELCOME

We are a research group in the Department of Mechanical Engineering at Virginia Tech, led by Assistant Professor Zhiting Tian. Our group seeks fundamental understanding of nanoscale energy transport processes in semiconductors, polymers, hybrid composites, and novel low-dimensional materials, as well as across solid-solid, solid-liquid and solid-polymer interfaces, for various applications including solar/thermal energy conversion and storage, thermal management of microelectronics, thermal insulation, and biomedical engineering. We conduct both simulations (ab initio and classical calculations) and experiments (ultrafast laser-based techniques and inelastic x-ray scattering) on nanostructured materials. We invite you to look at the website for more details.
