DESCRIPTION:The existence of Non-Fermi liquids which are not d
 escribed by Landau's Fermi liquids is a fascinatin
 g puzzle in theoretical physics. In this talk\, I 
 will show universal field theories where we can go
  around the Landau's Fermi-liquids and obtain Non-
 Fermi-Liquid behavior. These field theories contai
 n dynamical singlet fermions which couple through 
 fermion bilinear terms to strongly coupled sectors
  which are characterized by its ``dynamical scalin
 g''. Suppose these strongly coupled sectors have g
 ravity dual (which is not necessarily anti-de Sitt
 er space)\, then by using powerful gauge/gravity d
 uality\, I will argue how these dynamical scaling 
 parameters determine the natures of the dynamical 
 singlet fermions in a very universal way\; These n
 atures include the existence of Fermi-/Non-Fermi l
 iquids\, sharp Fermi-surface\, the decay rates and
  breakdown of the quasi-particles description. I w
 ill end with discussion for generalization of our 
 work to include the lattice effects and impurities
  for more interesting condensed matter system.
