Partner Preferences

In one line of research, Sierra investigates (a) the qualities people desire in relationship partners (e.g., attractiveness, warmth), the mechanisms underlying those preferences (e.g., sexual desire), and the implications of those preferences for established relationships (e.g., relationship quality).

Dyadic Influences

In a second line of research, Sierra investigates the individual differences that both partners bring into their relationship (e.g., attachment insecurity) and how they dynamically interact to influence crucial relationship processes and outcomes such as satisfaction and stability.

Threats to Relationship Maintenance

In a third line of research, Sierra investigates individual differences and processes that could undermine the maintenance of romantic relationships such as unrestricted sexual motivations and the presence of attractive alternative partners.
