We have developed a three dimensional Monte Carlo photoionization code
tailored for the study of H II regions and the low density ISM. The
code is described and benchmarked against other codes in
Wood, Mathis, & Ercolano (2004). This code was developed so we may
analyze
Ron Reynolds' WHAM data with three dimensional photoionization
techniques. Joanna Barnes is a PhD student in St Andrews working on
photoionization modeling of density grids from MHD simulations of a
supernova driven urbulent ISM. Some recent talks on our work are
presented here
