We present the most recent optical and near-infrared photometric monitoring of KH15D, a pre-main sequence binary star system that undergoes occultation by a precessing high-inclination circumbinary disk. Amplitude variations in the object's periodic light curve may be accounted for by the dependence of reflectance properties of the disk on distance from the binary or by a putative third body within the system. We have acquired medium-resolution spectra intended to probe circumstellar absorption features for signatures of mineral condensates for our study of this object's proto-planetary environment.
