Research Projects

Energy Storage
tomography rendering of region inside 18650 cell
Energy storage is a key part of the future energy landscape. How can X-ray help us probe inside batteries to make them hold more charge?
X-ray imaging and microscopy
How can we improve X-ray imaging and microscopy to make it fast, higher resolution, and more informative?
Additive Manufacturing
3D metal printing or additive manufacturing allows us the flexibility to print geometries impossible with traditional manufacturing techniques.

Who we are...
