  This thesis describes two lines of work. The first line is a study of the
application of transport theory to massless particles, such as the partons in
an ultrarelativistic collision at RHIC. The second line of work is an
application of imaging techniques to extract the relative distribution of
emission points from two-particle correlation functions measured in heavy-ion
reactions. This thesis contains an introduction to transport theory and
intensity interferometry as well as updates to several papers. These papers are
