Join us for this edition of the Faraday Discussion series. The Faraday Discussions are unique international discussion meetings that address current and emerging topics at the forefront of the physical sciences. This meeting is for established and early-career scientists and postgraduate working in the area of electronic structure. It will provide an ideal forum to reflect on where the field is, and the grand challenges which remain to be tackled, in order to extend its applicability to wider communities. On behalf of the organising committee, we look forward to welcoming you to London, or if you are joining us virtually, online.
