  We present a large N solution of a microscopic model describing the
Mott-Anderson transition on a finite-coordination Bethe lattice. Our results
demonstrate that strong spatial fluctuations, due to Anderson localization
effects, dramatically modify the quantum critical behavior near disordered Mott
transitions. The leading critical behavior of quasiparticle wavefunctions is
shown to assume a universal form in the full range from weak to strong
disorder, in contrast to disorder-driven non-Fermi liquid ("electronic
Griffiths phase") behavior, which is found only in the strongly correlated
regime.
