  In this thesis we investigate quantum mechanical effects to various aspects
of gravitational collapse. These quantum mechanical effects are implemented in
the context of the Functional Schr\"odinger formalism. The Functional
Schr\"odinger formalism allows us to investigate the time-dependent evolutions
of the quantum mechanical effects, which is beyond the scope of the usual
methods used to investigate the quantum mechanical corrections of gravitational
collapse. Utilizing the time-dependent nature of the Functional Schr\"odinger
formalism, we study the quantization of a spherically symmetric domain wall
from the view point of an asymptotic and infalling observer, in the absence of
radiation. To build a more realistic picture, we then study the time-dependent
nature of the induced radiation during the collapse using a semi-classical
approach. Using the domain wall and the induced radiation, we then study the
time-dependent evolution of the entropy of the domain wall. Finally we make
some remarks about the possible inclusion of backreaction into the system.
