Dr. Yongming Han is a full professor at the Institute of Earth Environment, Chinese Academy of Sciences (CAS). His research focuses on the use of biomass burning and fossil fuel markers to study environmental and climate change. Han has established dynamic links between wildfire and climate change, and investigated high-resolution atmospheric time-series in relation to the sedimentary records of black carbon (BC), combustion products, and other substances. Through his work he developed a thermal/optical method that enabled the separation of BC into two fractions (char and soot) and investigated their different roles in environmental pollution and climate change. He used the technique to distinguish between flaming and smoldering combustion in wildfire reconstructions and demonstrated clear glacial-interglacial cycles of flaming fires during the Quaternary. From the perspective of wildfire history, he proposed that wildfire provided macro-nutrients to marine biota that in turn affected atmospheric CO2. Han has been awarded 16 grants from the National Natural Science Foundation of China (NSFC), CAS, and the Ministry of Science and Technology. He is currently leading a project on the Anthropocene in China funded by the NSFC.
