Jiazhi is using tree rings technics to reconstruct (1) past climate variations — including temperature, precipitation, dry and wet changes; (2) and past geomorphic events , such as catastrophic debris flows. Throughout these objectives, combined with instrumental data, his aims are to analyze, identify and qualify the mechanisms that leads to the realization of past disasters.
Jiazhi obtained a Bachelor at the Tibet University, in collaboration with the the Wuhan University. He also obtained a Master’s degree at the University of Chinese Academy of Sciences.
His main ongoing research focus on reconstructing past disasters on the basis of instrumental data to understand their mechanisms and their frequency, in the Qilian Mountain area, China.
Currently, Jiazhi is completing his PhD at the University of Geneva’s Institute for Environmental Sciences (ISE).
