Dr. Justin Garcia is an evolutionary biologist and sex researcher. He trained under Dr. David Sloan Wilson (SUNY Distinguished Professor of Biological Sciences and Anthropology, Binghamton University) and then conducted a National Institutes of Health T32 postdoctoral research fellowship under former Kinsey Institute Director Dr. Julia Heiman (Professor of Psychological and Brain Sciences & Professor of Clinical Psychiatry, Indiana University). His research program focuses on the evolutionary and biocultural foundations of romantic and sexual relationships across the life course.

Garcia and colleagues have conducted research on a variety of topics related to social and sexual behaviors and intimate relationships, including variation in monogamy, intimacy, gender, courtship, dating, desire, satisfaction, and reproductive strategies. A specialist in interdisciplinary collaboration, Garcia’s research draws from and cuts across multiple fields of study. This approach aids his lab's exploration of the relationship context of sexuality, including the meaning, expression, and impact of romantic and sexual attitudes and behaviors.

 Since 2010, Garcia serves as Scientific Advisor to Match.com. In this role, Garcia provides expertise to Singles in America (SIA), the online dating company's annual study on the attitudes and behaviors of single people in the United States.
