I. Personal Profile
He, Keyang, male, born in March 1991, native of Linyi, Shandong Province. He graduated from Shandong University with a bachelor's degree in archeology in 2012 and received a Ph.D. in Quaternary Geology from the University of Chinese Academy of Sciences in 2019. From 2019 to 2023, he worked as a postdoctoral researcher at the Institute of Geology and Geophysics, Chinese Academy of Sciences. In May 2023, he joined Sichuan University as a specially-appointed associate researcher.
His main research interests are environmental archeology, using "multi-proxy microfossil" and "archaeological big data quantification" analysis methods to carry out research on paleoecological environment reconstruction, agricultural origin and dissemination, and prehistoric human-land relationships. His main achievements have been published in international and domestic authoritative journals such as Quaternary Science Reviews, Earth System Science Data, The Holocene, Boreas, Frontiers in Plant Science, and Science China: Earth Sciences.

III. Research Direction
Research fields: Environmental archeology, agricultural archeology, paleoecology, pollen analysis, phytolith analysis
Main scientific research achievements:
[1] Application of multi-proxy microfossil analysis in paleoecology and environmental archeology:
Synchronously applying pollen, phytolith, and diatom analysis methods to sites such as Jingtoushan, Hemudu, Yushan, and Liangzhu in the lower reaches of the Yangtze River, revealing the diverse environmental evolution processes of tidal flats, wetlands, and lagoons, elucidating the water environmental changes caused by Holocene sea-level fluctuations, resulting in cultural discontinuities in the late Jingtoushan (~7 ka BP), mid-Hemudu (~6 ka BP), and late Liangzhu (~4.2 ka BP) periods; proposing that the Younger Dryas cold event and the mid-Holocene marine transgression event caused three interruptions in rice domestication at 13-10 ka, 7.9-7.4 ka, and 6.4-5.6 ka BP.
[2] Construction and quantitative analysis of prehistoric plant and 14C archeological databases in China:
Constructed an archeological database including agricultural site points (n=1453), flotation results (n=544), and 14C dating (n=6756), outlining the development process of the prehistoric dualistic agricultural pattern and the rice-dryland mixed farming model in China, clarifying that three north-south exchange channels were formed between the upper, middle, and lower reaches of the Yellow River and the Yangtze River in the rice-dryland mixed farming system; high-precision quantitative reconstruction of agricultural and population fluctuations in the six major cultural regions of China around 4 ka, revealing that the millet and rice cultures in prehistoric China showed an opposite pattern in response to the 4.2 ka cold event; visualized the process of the shift from broomcorn millet to foxtail millet in northern China around 6 ka BP.
