Functional Approach to Phase Space Formulation of Quantum Mechanics
  We present BRST gauge fixing approach to quantum mechanics in phase space. The theory is obtained by $\hbar$-deformation of the cohomological classical mechanics described by d=1, N=2 model. We use the extended phase space supplied by the path integral formulation with $\hbar$-deformed symplectic structure.
