Liang Guo

 Liang Guo A/Prof

Research Areas:Nanoscale Energy Conversion and Transfer, Laser processing

Liang Guo received Bachelor degree in mechanical engineering, Tsinghua University in 2009. He conducted graduate research on nanoscale heat transfer in Mechanical Engineering, Purdue University. His projects include heat transfer across metal-dielectric interfaces, wavelength tuning effect in time-domain thermoreflectance for measuring thermal properties, and phonon dynamics in thermoelectric materials. He obtained PhD degree in September, 2014. From October, 2014 to July, 2017, as a postdoctoral researcher, he utilized femtosecond two-dimensional electronic spectroscopy (2DES) to study energy transfer in novel two-dimensional semiconductors in chemistry, University of California, Berkeley. His current project is exciton dynamics in monolayer transition metal dichalcogenides (TMDCs). Since 2012, he has published 10 papers listed in SCI/EI, 7 of which are first-author. He will join mechanical and energy engineering of South University of Science and Technology of China in August, 2017.
