Dr. Bai Song is an assistant professor in the College of Engineering at Peking University (PKU), Beijing, and a Co-PI at the Beijing Innovation Center for Engineering Science and Advanced Technology. He is also supported by the Thousand Young Talents program. Prior to PKU, he worked as a postdoctoral associate in the Mechanical Engineering Department at the Massachusetts Institute of Technology. He earned his PhD in 2015 in Mechanical Engineering at the University of Michigan, Ann Arbor, where he was honored with the ProQuest Distinguished Dissertation Award. He obtained his ME and BE at Tsinghua University, Beijing, and was a recipient of the Distinguished Master Thesis Award. He explores anything with an interesting thermal aspect, with a primary focus on the experimental, computational, and theoretical study of heat generation, transport, conversion, and storage, in diverse materials, devices and systems, and especially at small spatial and temporal scales. He further aims to leverage such knowledge to develop engineering solutions to real-world challenges in key areas including energy and environment, electronics and optoelectronics, quantum materials, and space exploration. He has published 3 papers in Nature and Science and 5 in their sister journals such as Nature Nanotechnology and Science Advances, on the fundamentals of nanoscale thermal radiation, phonon localization and second sound, and semiconductors and polymers of unusual high thermal conductivity.
