I am a social psychologist in the Department of Psychology at Harvard University, where I teach and conduct research in the areas of relationships, prejudice, and sexuality. I also run a popular blog entitled "The Psychology of Human Sexuality" where I present the latest sex research in a way that is engaging and accessible as well as answer readers' questions.

To date, I have published over 30 scholarly works, which includes several articles published in the leading journals on sex and relationships, multiple book chapters, and two textbooks. Most of my research publications fall into one of two areas. One of these areas examines commitment to interpersonal relationships, including both romantic relationships as well as casual sexual relationships (e.g., "friends with benefits"). I am interested in the factors that influence how commitment to these relationships develops and changes over time, as well as the consequences of commitment for the health and well-being of the partners involved. My other main area of research concerns prejudice and discrimination, especially as they pertain to sexuality and relationships. My recent work on this topic has focused on how perceptions of bias against one's sexual orientation and relationship status influence physical and psychological well-being and engagement in risky health behaviors. Across all of this work, my goal is to conduct theoretically grounded research that has the potential to address important social problems.

My research has been featured prominently in numerous media outlets, including the Huffington Post, Psychology Today, Men’s Health, The Globe and Mail, and The Sunday Times. I have also appeared on a few episodes of the television program Taboo (produced by National Geographic) to talk about the science of sex and relationships.
