DESCRIPTION:We study the Lyapunov exponent in disordered quantum field the
 ories. Generically the Lyapunov exponent can only be computed in isolated 
 CFTs\, and little is known about the way in which chaos grows as we deform
  the theory away from weak coupling. In this talk we describe families of 
 theories in which the disorder coupling is an exactly marginal deformation
 \, allowing us to follow the Lyapunov exponent from weak to strong couplin
 g. We find surprising behaviors in some cases\, including a discontinuous 
 transition into chaos. We also describe a new method allowing for computat
 ions in nontrivial CFTs deformed by disorder at leading order in 1/N.
