Welcome!

Welcome to the research website of Zherui Han, a postdoctoral scholar in Professor Eric Pop’s group at Stanford University. Previously, I did my PhD within Sustainable Energy and Nanoscale Transport Laboratory led by Professor Xiulin Ruan in the School of Mechanical Engineering at Purdue University. My research is to advance the understanding on phonon dynamics and thermal transport for the benefit of a sustained energy future.
