DESCRIPTION:Maximal supergravity in two dimensions enjoys an infinite-dime
 nsional rigid symmetry group\, E_9\, that generalises the Geroch group of 
 pure GR with two isometries. We may break this symmetry by gauging. This g
 ives rise for instance to SO(9) gauged supergravity\, relevant for the hol
 ographic description of the D0 brane matrix model. A vast\, unexplored lan
 dscape of other theories is available which can capture features of many o
 ther black-hole models. The full formulation of their dynamics and their s
 tring theoretic interpretation were however lacking. I will describe the f
 ull (bosonic) construction of these theories and the framework necessary t
 o related them to consistent Kaluza--Klein compactifications of ten- and e
 leven-dimensional supergravities. I will summarise the map from D0 brane g
 eometries to SO(9) gauged supergravity as well as some ML-like techniques 
 useful to explore the landscape of 2d gauged supergravities.
