1993-1999I studied geology in the first base class of the Department of Geology at Northwest University in my year, with a combined bachelor's and master's degree.1996Year,1999Obtained bachelor's and master's degrees respectively,2003Obtained a Ph.D. in Paleontology and Stratigraphy from Northwestern University in 2003.Lecturer in the Department of Geology at Northwestern University from 2003 to 2007; Associate Researcher in the Department of Geology at Northwestern University from 2007 to 2015; Visiting Scholar at the University of G ö ttingen, Germany from September 2009 to March 2010; Researcher in the Department of Geology at Northwestern University since March 2015. Conducted extensive international collaborative research and joint doctoral training with Cambridge University, University of Tokyo, Kyoto University, Hiroshima University, Lyon University in France, and Hanoway College in the United States.

Engaged in research on the Cambrian Explosion of Life and the Evolution of Animal Species, focusing on the early Cambrian Chengjiang Biota (518Ma), Kuanchuanpu biota (535Ma have achieved a series of important results. Main achievements: 1) Discovered the oldest known animal incubation behavior, scavenging behavior, and carnivorous swimming jellyfish with sensory sticks in the Chengjiang animal group. 2) The oldest known sea anemone fossil with preserved soft body structure and the soft tissue structure of jellyfish embryo fossils with four or five radiation symmetry were discovered in the Kuanchuanpu biota. 3) The oldest known molting behavior has been discovered in the Kuanchuanpu biota4) Microcystis coronata was found in the early Cambrian Kuanchuanpu biota, suggesting that there may be more sister genera and other unknown micro" cousin "types with mouths but no anus to be discovered at the bottom of the Cambrian or even in the late Pre Cambrian
