I am a social psychologist who studies sexuality and romantic relationships. The primary goal of my research is to understand the factors that contribute to people having more satisfying sexual and romantic relationships. In one line of research, I use approach-avoidance motivational theory to understand when sexuality is rewarding and when it detracts from relationship quality. In another line of research, I consider how individual differences in the motivations to meet a partner’s sexual needs influence both partner’s sexual and relationship quality. In a third line of research, I examine the daily activities that promote intimacy and passion in couples’ relationships. In a fourth line of research, I consider how the information people share online influences their satisfaction and commitment in romantic relationships.
