The group of Deep Life constructed a scientific framework for the temporal and spatial evolution of deep-sea microorganisms. The main achievements are as follows:

Based on Big data of global marine microbial genomic, analyzed the classification of microbial groups, metabolic characteristics and evolutionary pathways of deep archaea and alkane-metabolizing archaea, which is the most abundant microbial groups in the global ocean.

Relying on deep-sea environmental simulation technology, the deep-sea unculturable microorganisms represented by anaerobic methane-oxidizing archaea and lignin-degrading bacteria were efficiently cultivated. The unique carbon transformation characteristics were discovered and validated, providing scientific evidence to assess the mechanisms of carbon turnover in marine environments.

Construct the model of deep-sea geochemical cycles which innovatively integrated bioturbation processes, organic carbon composition, and gene sequencing data. The scale of the carbon-nitrogen cycle in typical ocean areas were assessed precisely. 

The above research results were published in top journals such as Nature Microbiology, Nature Communications, and Science Advances, and have been selected twice as ESI highly cited paper.
