Why are some couples able to keep their sexual spark alive and have fulfilling romantic partnerships over time while other couples are disconnected and discontent? Dr. Muise’s research focuses on understanding how couples can maintain happier relationships and have more fulfilling sex lives over time. In her research she applies social psychological theories of close relationships and motivation to understand when and for whom sex is associated with benefits and when it might detract from the quality of relationships. She uses dyadic and longitudinal research methods and analyses (i.e., daily experience studies, multi-level modeling) to understand how sexual processes unfold to impact relationship well-being in the context of couples’ daily lives as well as over the course of time as relationships grow and develop.

Dr. Muise is interested in understanding these processes not only when couples are doing well, but also when they are navigating relationship transitions, such as the transition to parenthood, or coping with a clinical sexual issue, such as low sexual desire. Recently, she has recruited samples of couples who are about to have their first child and clinical samples of couples who have been diagnosed with a sexual problem. Her interest lies in understanding the individual and relationship characteristics that help couples navigate relationship changes and challenges with greater success.

Finally, although most of Dr. Muise’s research is focused on a private domain of relationships—sexuality—she has another line of research on public displays of relationships. The rise of social media has changed two main things about romantic relationships—our ability to access information about our romantic partners and additional opportunities to display our relationships publically. In her work on the relational effects of social media, she has investigated the costs and benefits of accessing relationship-relevant information and sharing information about a relationship on social media.
