Working with AAVSO data and AAVSO staff on cataclysmic variables since the 1980s resulted in twenty-nine papers from 1984 to 2011. The early work began with characterization of optical light curves of various dwarf novae and novalikes, then moved into coordination of optical observations with satellites (IUE, EUVE, XMM, Chandra, HST, GALEX) to explore the ultraviolet and X-ray regimes of disk systems versus those containing magnetic white dwarfs. The major advances in the field that were derived from these results are summarized, ending with the recent results on the cooling of the white dwarfs and the return of pulsations in GW Lib and V455 And following their 2007 outbursts, and on the spectra of the two peculiar Z Cam systems IW And and V513 Cas.
