Research Interests

It is still a puzzle where and how the life was originated on early Earth about 3.8 billion years ago. Using DNA/RNA, proteins/peptides, polysaccharides, fatty acids, and other biomolecules as the raw materials, our group is to construct protocells with hierarchical structures via spontaneous physical processes like self-organization and phase separation, and to achieve “living” features such as metabolism, growth and division, and evolution. We expect to reveal the transition mechanism of non-living to living matter, as well as the possible approach of origin of life on early Earth. The current research projects in our group include, but not limited to:

  • Formation and dynamics of coacervate protocells on mineral surface

  • Effects of macromolecular crowding and confinement on dynamics of coacervate protocells

  • Construction of coacervate protocells and their behaviorsunder extremeconditions

  • Origin of homochirality in living cell
