Dr. Bo Sun currently is a faculty member in Tsinghua-Berkeley Shenzhen Institute (TBSI). He was a postdoctoral scholar in Department of Mechanical and Civil Engineering, California Institute of Technology from 2016-2018 with Prof. Austin Minnich. He obtained his PhD from National University of Singapore in Mechanical Engineering in 2016, M.S. in Chemistry and B.S. in Physics, both from Shandong University.
His research interest is thermal sciences and nanoscale heat transfer. He is an expert on time-domain thermoreflectance (TDTR), an experimental technique for thermal transport properties. His previous work mainly focused on thermal transport in low dimensional structures such as 2D Black Phosphorus and quasi 1D perovskites, as well as phonon transport mediated by lattice imperfections such as dislocations. He is the first to discover frequency-dependent thermal conductivity in van der Waals crystals and his research on dislocations mediated thermal transport is “a piece of pioneering work in our field”.
He is the 2017 Wang Gungwu Medal nominee in Singapore. He also severs as the reviewer for journals such asPhys. Rev. Lett., Nature Communications, PNAS, ACS Nano etc.

Research Expertise and Interest
Nanoscale Heat Transfer, phonon transport, Thermal Sciences, Materials Physics and Optical Techniques
Research Description
My research is in nanoscale energy transport. Weexplorephonon transport mechanisms in materials and in nanostructures. Specifically, we are investigating on:
i) Mechanisms of heat transport in nanostructured solids
ii) Thermal transport across solid/solid and solid/liquid interfaces
iii) Thermal transport under extreme conditions

An ultrafast pump-probe technique, time-domian thermoreflectance (TDTR) has been built for experimental studies of thermal transport properties of materials. For details of my publications, please see Google Scholar.  We are also planning to build a new setup, time-resolved magneto-optical Kerr effect (TR-MOKE), for future studies on thermal induced ultrafast magnetism and spin current.
