Cassini specializes in gender and sexuality. Her book, Compensated Dating: Buying and Selling Sex in Cyberspace, investigates Compensated Dating practitioners’ self-identity, desire and their dynamic relationships. In addition to the stories of female providers, her book explores the life-experiences of male clients, which is under-reported in the current literature of compensated dating in Asia. Through her interviews and ethnographic work, her book unfolds how modern intimacy entwines in the on-line and off-line worlds.
