Joseph researches directed assembly methods for the preparation of vertical arrays out of randomly oriented microwire ensembles, primarily using magnetic fields. This research is a step on one possible route for bringing the fabrication of electronic devices, such as solar cells, out of the cleanroom and towards scalable production.
