Hau and Harris revolved mainly around electromagnetically induced transparency and slow / stopped light (in ultracold gases) ... topological slow light, rainbow trapping, and solid-state slow light (at ambient conditions) sound more intriguing to me, and seem to have a variety of tangible...
If it is Lene Hau (slow & stopped light) she probably won't be alone - maybe with the rainbow-trapping guys (Tsakmakidis / Hess) ?? who knowns ... that would be a good and surprising choice.
