Research Areas

The research in Chen group is cross-disciplinary, bridging up mechanical engineering, chemistry and materials science, focusing on electrochemical energy storage related materials and devices, as well as functional and structural metals/alloys. The technical expertise of the group include development and application of advance in situ characterization methods for energy storage devices, computation-aided materials design and novel synthesis methods for nanostructured materials.


 

Research Area 1:

The experimental methodologies for “Materials by Design” (e.g. the Materials Genome approach), including high-throughput synthesis and in situ XRD for synthesis.
