Research Interests

My research interests include evolutionary and cross-cultural  approaches to understanding personal relationships, sexual strategies, romantic attachment styles, and gender differences in human mating. 

I am also interested in the "Big Five" model of personality traits, risk factors for HIV/AIDS, and predictors of both sexual aggression and  intimate partner violence across cultures. 

I am Founding Director of the International Sexuality Description Project (Schmitt  et al., 2003), a cross-cultural survey that included samples from 56  nations representing six continents, 13 islands, and 28 languages. A second wave of the ISDP, the ISDP-2, includes more than 200 collaborators and 58 nations.
