His research interest is mainly focused on the biomolecular self-assembly and materials, mesoscale mechanisms, biomimetic protocells and functional architectures for biomedicine and bioenergy. These include the engineering and assembly of chemical or biological nanoreactors as biocatalysts and vaccine adjuvants; and the development of new-type drug delivery vectors, nanomedicine and formulation towards application of phototherapy and immunotherapy etc. against tumors; as well as the creation of model abiotic cellularity and biomimetic protocells for study of prebiotic photosynthesis and biochemical process in cells.
