Professor Herek's work focuses on issues of prejudice and stigma, especially as they apply to sexual orientation and HIV/AIDS. His major research projects have included studies of sexual prejudice in the US population, the mental health consequences of hate crimes against lesbians and gay men, and the impact of stigma on sexual minorities and people with HIV/AIDS.
In the policy arena, he has contributed extensively to amicus briefs filed by the American Psychological Association (APA) and other professional associations in court cases concerning marriage equality for same-sex couples, sodomy laws, military personnel policy, and other issues. In addition, he has served as a consultant and expert witness for numerous legal cases involving the civil rights of lesbians and gay men and people with AIDS. Examples include Perry v. Schwarzenegger, in which California's Proposition 8 was declared unconstitutional, and Pickup v. Brown, in which a California law prohibiting state-licensed mental health providers from attempting to change the sexual orientation of minors from homosexual to heterosexual was upheld.
A Fellow of the APA and the Association for Psychological Science, Professor Herek received the 1996 APA Award for Distinguished Contributions to Psychology in the Public Interest, and the 2006 Kurt Lewin Memorial Award from the Society for the Psychological Study of Social Issues (APA Division 9). In 2010, he received the Distinguished Scholarly Public Service Award from the UC Davis Academic Senate, and the Distinguished Humanitarian Contribution Award from the California Psychological Association.
