The presence and prevalence of massive black holes in dwarf galaxies may hold clues about the formation mechanisms of supermassive black holes, which appeared at the earliest epochs. However, finding massive black holes in dwarf galaxies is exceedingly difficult owing to their low accretion luminosities. Unique methods are needed to disentangle the accretion signatures of massive black holes in active galactic nuclei from bright stellar populations, and several new promising methods have been developed in the last decade to find these elusive objects. In this talk, I will discuss our recent work exploring the use of mid-infrared photometric variability to find active galactic nuclei in dwarf galaxies.
