The research interest focuses on the interdisciplinary field of biochemical engineering, biocatalysis, and bioelectrocatalysis. In general, we use the tools and principles of synthetic biology, bioelectrochemistry, and bionanotechnology to investigate fundamental sciences behind biocatalysis and electron transfer, and construct bioelectrocatalytic systems including enzymatic biofuel cells, biosensors, and enzymatic electrosynthesis for real applications. We hope our research could shed some light on the mechanism of bioelectricity generation and utilization, and solve some challenges in the areas of portable or implantable electrical energy supply and sensing for human health or biomanufacturing.
