DESCRIPTION:Finding consistent truncations of 10/11-dimensional supergravi
 ty is a notoriously difficult problem. Exceptional field theory\, a rewrit
 ing of supergravity which treats p-form and metric degrees of freedom on t
 he same footing\, has recently been shown to be a powerful tool in constru
 cting new maximally-supersymmetric consistent truncations and proving the 
 consistency of the famous S^4\, S^5 and S^7 truncations of 10/11-dimension
 al supergravity. In this talk\, I will review these developments and show 
 how to generalise the approach to obtain half-maximal consistent truncatio
 ns. I will also prove a conjecture by Gauntlett and Varela that any half-m
 aximally supersymmetric warped AdS solution of 10/11-dimensional supergrav
 ity admits a consistent truncation to the graviton supermultiplet. If time
  permits\, I will also show how the methods introduced allow one to study 
 the moduli of half-maximal AdS / Minkowski flux vacua.
