A graduate of the Columbia Law School, Huq clerked for Judge Robert D. Sack of the Second Circuit Court of Appeals and Justice Ruth Bader Ginsburg of the U.S. Supreme Court. He then directed the Brennan Center for Justice’s work on civil liberties and national security. At the Brennan Center, he was counsel in several Supreme Court cases, including Omar v. Geren and al-Marri v. Spagone—both involving indefinite military detention of “unlawful combatants.” He also advised Muslim, Arab, and South Asian community groups on responses to terrorism-related policing matters. In 2006, Huq was awarded a Carnegie Scholars Fellowship to study the effect of criminal counterterrorism regulation on religious speech and practice in the U.S. He is also a principal investigator on a project funded by the National Science Foundation on the effects of counterterrorism policing on Muslim communities in London and New York.
