Suchitra Sebastian studies quantum matter, and in particular - superconductors.
Superconductors are already in use throughout modern day life - they're found in MRI machines, and at the LHC at CERN, amongst others. However they often have to be kept at very low temperatures (requiring power-hungry refrigeration systems) or else they lose the superconductivity.
By researching and developing our knowledge of these systems, we might one be able to use superconductors to replace the existing cables that link together power stations and homes. For example, linking wind farms deep in isolated areas to urban areas, without energy being lost in the cables along the way.
