Halberstam was the Associate Professor in the Department of Literature at the University of California at San Diego before working at USC. Halberstam is a gender and queer theorist and author.

His writings focus on the topic of tomboys and female masculinity and his 1998 book, Female Masculinity, discusses a common by-product of gender binarism, termed "the bathroom problem.″ This outlines the awkward and dangerous dilemma of a perceived "gender deviant's" justification of presence in a gender-policed zone, such as a public bathroom, and the identity implications of "passing" therein. Assigned female at birth, he accepts masculine and feminine pronouns, and the name "Judith" in addition to "Jack," for himself.
