At the current time, there are 12 white dwarfs in cataclysmic variables that have shown evidence for pulsations. We are investigating how their pulsation properties could be different than for single, non-accreting white dwarfs due to their presence in these accreting close binaries. Our work includes results from coordinated HST ultraviolet and ground-based optical observations to determine the temperatures of the white dwarfs and their location in an instability strip, as well as a coordinated campaign on SDSS1610-01 and an observing program on GW Lib and V455 And after both systems underwent dwarf nova outbursts in 2007.
